Windows works on the new MacBook not because it has special drivers for NVMe-via-T2 but because Apple trusts Microsoft's EFI key.

So no, stop it with all this "Linux works if you just disable Secure Boot" nonsense. It doesn't. You can run Linux from a USB key, sure, but it can't access the internal NVMe SSD!

Judging by this post:

It looks like some kind of driver issue, not an intentional lockout.

To corroborate this, while I don’t have personal experience running Linux on T2 devices, I do know it’s possible to build xnu from source and boot the resulting unsigned kernel (in “No Security” mode) without the disk disappearing.

Please provide evidence for this causal link. It is true that (with Boot Camp enabled) the firmware trusts the Windows key and not the MS third-party key. It is true that Windows can access the disk and Linux cannot. It is not obvious that these are related.
