There's others reasons why you want as much heat dissipation as possible, as wide as possible in a high end camera, however. Many cameras are limited in their 2160p30 and 2160p60 video recording times by heat build up. Also now 6k and 8k capable cameras. The cooler your cfexpress card can run, the less cumulative watt hours built up in the camera body during a "long" 20-30 minute recording session.
Some that are designed with a focus on video recording have active cooling and fans for the cpu and sensor, such as the new Panasonic gh6, or a red Komodo.
I worry that there's a hidden issue with maximum power draw. If the camera supplies less maximum current than the drive could potentially draw from an M.2 slot, you might see the card crash in certain situations. This could be the kind of very annoying thing that works fine in testing but fails in on specific scenario in real-world use.
Ideally, SSD manufacturers would program their SSD firmware to provide multiple active power states accurately labeled with their maximum power draw, and cameras would select only power states that are within their power delivery constraints. All of this functionality is already defined and standardized. But I'm pretty sure neither side is taking it seriously enough to be relied upon.
IIUC, CFExpress is just a PCIe interface in a different form factor, so the adapter in the post should basically just be a pass-through. Conversely, a USB-C adapter would require some level of protocol adaptation/electronics/etc.

Probably because you valued your time at zero.
At a minimum probably 30 minutes to buy the components - although realistically with the shortages at the moment might take longer because you'll have to look around for places with stuff in stock.
Then let's say 20-30 minutes to get the components in place (I'm including packaging removal time here).
Plus a bit more for testing, labelling etc.
Sure it's not the most labour-intensive thing in the world, but the time soon adds up.
And that's assuming everything works first time and you don't have to spend time troubleshooting or returning broken components.
What hourly rate does your salary work out to ? ;-)
The difference between the parts and shipping (±$90) and a comparable CE card (±317) is $227. Assuming three hours of work including research you'd need to earn about $75 per hour to break even. Assuming a 40 hour work week, 4 weeks of holiday time and no other benefits, that amounts to a yearly wage of $144000, placing you firmly in the top 1% of the world, and the top 10% of the USA (according to https://www.compareyourincome.org/)
After taxes, my current salary comes down to about €12,28 per hour (≅$13.27). Not a great rate, but higher than 36% of the rest of my country assuming a full time working week. That means I can work at least 17 full hours on such a project and end up making a profit. The 30-60 minutes of work that this project takes saves me over $200.
Most of the world doesn't work for the ridiculous rates FAANG pays. Good for you that you're too rich to even bother about spending $200 extra for a memory card. However, your skewed expectations don't detriment the value of this article in any way.
CFexpress cards are considerably more expensive than other similar forms of storage like SD cards — a comparable 256GB CFexpress card currently goes for $259.99 [0]. From a pure cost perspective, it could very well be worth it. As a hobby photographer I would consider doing this for the fun of it anyway.
I think you're overestimating the time required to do this. It looks like 30 minutes to me, all-inclusive.
The cheapest no-name 256gb cards are $130 on Amazon, so that works out to $60/hr assuming the DIY version is no better than no-name. Big brands cost twice that, so if the DIY version is equivalent quality to those, $320/hr.
If I work at a fixed salary, my effective hourly rate isn't relevant here. I can't spend the time I saved to earn more money. My only choices are spend less on DIY or spend more on ready-made.
The right discussion here is opportunity cost: what did I have to give up to use my time or money this way? That depends more on my bottom-line discretionary funds and free time than on my top-line salary.

Neat. Is there a comparable NVME 2230 enclosure with USB-C external connector for use in laptop USB4/Thunderbolt ports?
That could combine SSD speed/reliability with the portability of a flash drive.

I have used this: https://www.amazon.com/gp/product/B07Z8Y85GL/
It works, but it runs hot so I added one of these: https://www.amazon.com/gp/product/B07WJVFQQ9
I've tested it with 8TB nvme flash. Don't know if it can support anything higher.
