I'm in particular commenting on the stat structure involved with the kernel interface.

And I'm pointing out that that you're not only excluding a whole major portion of the kernel ABI from this mechanism if you do that, you're effectively requiring new mechanisms every time something is included into POSIX over time! If that isn't insane, I don't know what is.
