I like this package. First, it's not being suggested for core, or as an
alternative to standard methods. Second, just because you *can* do something
in a manual way, is no reason to argue against convenience. I would both
welcome this addition, and start using it.

As a bonus, it could be implemented as a macro that does actually generates a
new function and adds that function symbol to the hook, in such a way that if
you change the body and re-evaluate with C-M-x, it removes the old function,
and adds the changed one. Then it would be identical to what "best practices"
say one should do when adding a hook, but with a clearer declaration of
intent: "I want the following FORMS to happen when the hook is run".
