Reopened for that, or failing that then for clarifying the docstring.

I imagine there's not normally many hooks or many buffers, or many
buffer-local variables, whichever one of those was the efficient way to
scan ... and unload-feature isn't used very much anyway.

(Actually the way unload-feature seems not much used and not getting
much attention from packages makes me wonder if it's worth bothering.
But if unload-feature did a little more then it would increase its
usefulness, perhaps to the point where it would be used more :-)
