We shouldn't spend time adding a feature to GNU Emacs
for the sake of running it on MacOS.

Nor Windows.  We should not implement features that are of no use
on the GNU system.

Since kitty runs on GNU/Linux, maybe it is worth implementing
this variant of the specification, for the sake of kitty.

It's a matter of weighing the work involved (development and
maintenance) against the benefits.

We could wait and see if this protocol catches on, on GNU/Linux.
If it does, it will surely be worthj supporting.
