Re: the ...-unload-hook convention doesn't work

[Richard Stallman]

It makes no sense to think about unload-feature in terms
of the cl package.  That is a very hard case.  Other cases
will work before that one does.

However, the motive for unload-feature had to do with
reclaiming memory.  With the other changes in size of machines,
size of disks, and size of Emacs address space, maybe that is
pointless.  Maybe we should eliminate unload-feature just
to make things simpler and avoid spending time on it.
