What's the rationale for populating the hook by default?  That's not
what we normally do: hooks are for Lisp programs to use, not for the
core functionality to invoke itself.

First, this is not a hook.

And second, if we want a feature whereby the buffer describing
bindings could be put in Outline mode, why not offer a simple option
for users to customize, not a hook for users to tweak?  Once again,
having user options that accept only function values is
user-unfriendly.

Thanks.
