Package: emacs
Version: 25.2
Severity: wishlist

I'd like to suggest removing support for the Motif toolkit.

Motivation:
Supporting more toolkits (gtk2, gtk3, lucid, motif, none) makes it
harder to develop relevant low-level features.

The Motif toolkit build of Emacs seems to be very little used:
  - Fedora packages just a Gtk version
  - Debian packages Gtk and Lucid
  - Only ~20 mentions of "motif" on bug-gnu-emacs, ever. Most are just
  comparison testing

(I see https://wiki.gentoo.org/wiki/GNU_Emacs mentions it, but my
suspicion is that this is just an attempt at completeness when listing
alternatives to Gtk. Since it's listed first, I wonder if this has
caused more people to use it than otherwise would. All just speculation
on my part.)

(The "none" toolkit is also never used in practice, but I understand it
may be useful as a base/reference.)

We agreed to keep Motif support in a discussion last December, so I'm
closing this bug.

I agree with Martin in that there isn't a single concrete case where
Motif interferes with the development of a feature.  Most of the
important code is shared with the Lucid/Athena build, since both
toolkits use Xt, and the toolkit that causes us difficulties is
typically GTK 3.  For instance, it's the only toolkit that has to be
special-cased for frame resize synchronization, since it doesn't behave
well when it doesn't know about the basic frame counter, while the
development of that feature went smoothly on every other build we
currently support.
