It isn't available on Haiku and doesn't work very well on MS-Windows,
macOS, and even GNU/Linux.

For example, it crashes during a display disconnect, fights with Emacs
over the size of frames, it cannot utilize selections when connected to
multiple displays, correctly position frames on X, warp the mouse
pointer, and so on and so forth.

The only use for GTK is to support window systems that we don't
otherwise support, such as Wayland and Broadway.  Otherwise, using that
window system directly will almost certainly lead to a better user
experience.
