Oh I agree with it being nice, I'm just imagining more socialization oriented resistance to implementation and both large organizations and hobbyists already have answers that mostly cover the use cases even if not exactly as cleanly. Moving node to node encryption to an accelerated implementation of transport mode would be great, but if you're already using TLS I can see people just sticking in TLS versus hoping both ends had the necessary handshake->ESP path working, plus people are more experienced with existing troubleshooting, etc.

It's still "TLS" as far as the application is concerned, which is why this could work, but yes, there are a few roadblocks, not the least of which is the absence of compelling HW. Another thing is that I/O is faster than compute nowadays, so making it faster may not be helpful :joy:
