Subject:      \clearpage and \AtEndDocument hooks
Status: R

There is commented-out code in latex.dtx that would issue a \clearpage
before executing end-document hooks if there are dangling floats.  The
text says that such clearing is controversial.

I have written some code for an end document hook (changebar), and
considered code for another (labelling the last page for `n of m' page
numbering).  In both cases, the hook would need the final \clearpage to
have been executed, so that the hook code itself needs to execute it
itself (in present circumstances).

If this is the case, and if executing \clearpage in latex itself is indeed
controversial (i.e., there are cases when you _don't_ want the \clearpage
before executing the hook), it seems to me that there's an argument for
two sets of end document hook, one executed before and one after the final
\clearpage.

As things stand at present, a hook that requires to be executed before the
final \clearpage needs to guarantee that it's in the correct place in the
hook, which leads us back to <= 2.09 hackery, imho...

So what's wrong with my reasoning?  What _is_ the controversy about the
\clearpage?
