I do not claim I am goot at naming (or better than you at it
anyway), but list-hooks sounds to me like it is calling printf()
to show the hooks to the user, not computing a list of hooks and
returning it to the caller.

Yes. The callsite becomes easier to understand, and it separates
the responsibility between the helper to respond to "please give me
list of defined hooks" and its caller that may react to the returned
list with "ok, among these hooks, this does not look kosher for such
and such reason, so I'd die/warn/error" much cleaner.
