Yes, that's what I meant by "return a new buffer".  They aren't forced
to return nil, BTW (although in practice, it seems they always do).

I don't propose a hook, but a buffer-local *-function (as opposed to
*-functions or *-hook).  I.e. a single function, just like your
proposal, except it's stored in the final "returned" buffer, rather than
returned explicitly.
