They mostly don't join in because they mostly never have. Either that or
they are content with the xforms frontend as is like most of the rest of
the developers (including me) have been for the past umpteen years.

I used to have a couple of simple macros to make it easier for people to
work with. You didn't have to think about what or why just name the type
of connection. It seems someone (probably Angus?) removed these several
months ago when most of the [xforms] dialogs moved to FormBase. I still
think they'd make life simpler for people adding the odd new dialog
specific callback but such things are rare so it may be best to just
expose the plumbing.

Don't we all?

Of course you will have read xforms/forms/README by now and realized that
Angus meant to write button_find_next and button_find_prev ;-)
