No, just the hooks.  If it makes sense to remove unloaded funcs from
hook global values then surely the same rationale applies to remove them
from the buffer-local values too.

Or conversely, it's undesirable to leave behind an unbound func in a
hook, and the same undesirability as to a buffer-local value as a global
value.
