It seems quite natural that the result of "sizeof" ought to be just
taking TYPE_SIZE_UNIT and converting it to the user-level type.
You're right that it's not strictly *required*, but it would seem best
if no sizing or signedness conversion were required in that case.
I don't think we're disagreeing from a "language lawyer" perspective,
