I don't think I know (or didn't know or at least don't
recall) anything about such a thing.  Is it something new?

Dunno what you mean by that ("share the bindings").
But maybe if I knew what "loading-on-completion" is
then I would understand "share the bindings" (?).

Maybe so, but then the question would be whether and why
dframe.el (or anything else) would initialize the hook
to have one or more functions on it.

In my case, I'm pretty sure I don't want anything other
than my replacement for iconification to be on the hook.
So I would probably empty the hook before using `add-hook'
for my function.  Maybe that's only out of ignorance of
what the deframe functions are for or do.

But (without looking at them), those sound like specific
replacements for the standard iconify etc.  If so, it's
great to provide such functions, but they shouldn't be
bound to special events by default (i.e., upon loading).

Yes, thank you.

I can't speak to the value of the patch (I know nothing
about this), but thanks for working on this.
