I tend to agree, consistency models were just a temporary idea that seems
to likely become unnecessary given all the ideas on the unified solution
that have been presented so far.

(Well, with a small exception to this -- I still think we should be able
to "fire and forget" for patches where it's guaranteed that no
housekeeping is necessary -- my favorite example is again fixing out of
bounds access in a certain syscall entry ... i.e. the "super-simple"
consistency model).
