Have you met some of the weird architectures with their super strange
VM extensions and the even weirder confidential computing extensions?

True (well mostly), but the internal complexity is concealed within an
external abstraction rather than having it spill all over the kernel
... I would hope DRM does the same.

If your assumption is correct, this is internal cat herding ... MM has
much the same problem except that it has to deal with somewhat
opinionated architecture maintainers (around 22 of them) to agree on
the internal abstractions for MM primitives.  Perhaps rather than
getting into my problem is bigger than yours type arguments, we could
observe that MM might run a bit more smoothly because it gets an
additional 3 day conference (LSF/MM) plus a MC at Plumbers to sort
itself out?
