The scenario I'm thinking of is where a package adds itself to a hook to
get itself auto-initialized.

If the hook isn't saved (eg: by customize) then of course the contents
will be lost.

That's all I meant. Customizable hooks are good for packages to hook
into (with enough user consent) because they are persistent.

That is a *really* good idea.

It's a brilliant solution I think.

I'd be happy to implement it (when we have git).
