Ah, that sounds like a more plausible explanation for the effect I
see.  That would mean that (require 'feature) can't be undone with
(unload-feature 'feature) concerning the autoloads.  And also all hook
variables are cleared.  This behavior has some sort of usefulness,
namely "get rid of that package and I don't want to ever see it
again", but I think the normal use pattern without extra options for
unload-feature would probably to restore the stuff to dormant, not
dead.

Probably.  I assumed Stefan was talking about a different hook, but I
can't see anything but the normal unload-hook, at least in
loadhist.el.
