I do not see why you'd think that "switching the default allocator out"
requires anything except making AllocSetContextCreate do something else.

What is actually of interest, IMO, is making *some* contexts have a
different allocator, and that is going to require case-by-case decisions
anyway.  A blanket switch seems completely useless to me.
