I definitely like the latter idea as wholly on-point for the main
issue this draft is trying to address, and will get it into the next
rev.

I'm slightly less sure about dragging delegating rechecking into it,
but open enough to being convinced that it is also on-point and
doesn't unduly complicate what is conceptually very straightforward in
the current draft.

I'm also in favour of revivificating resimprove.  I don't know why it
languished either, but don't recall substantial objection.  If it were
brought back that somewhat obviates needing to bring up the delegation
recheck here.
