The now-obsolete functionality (for FOO-unload-hook, not
unload-feature in general) was confusing, badly designed and
ill-documented; changing it would have been backward incompatible, not
to mention fragile. It was better to add a new way. The current
FOO-feature-function was added because in most cases, it's the
package's responsibility to know how to unload itself. For the few
cases that do not, there's always advising; but perhaps
`unload-feature-functions' would be a good idea, and there's no worry
about compatibility.
