As simple as a different default value for :initialize?
That idea is not my design, it is yours. It should be much simpler
and safer than changing add-hook as I suggested, and it should have
the same benefit (allowing non-nil default values).
The UI would warn that the hook has been "changed outside customize",
which I assume is correct if we want the behaviour (of Lisp packages
setting user options) to continue to be deprecated.
If it works, I think it still would be a cleaner API if this was done
with a `defhook' declaration, rather than having :type specific code
in `defcustom'.
