That is indeed a worry.

There's no set rules for any of this -- but we want Emacs to be as
usable as possible across as large a number of systems as possible.
This means that we have a lot of special purpose code in Emacs to work
around oddities in systems, and to interact with specific systems and
libraries.

Sway seems to be one of the major players in the Wayland world, so I'd
welcome code to make Emacs work better under Sway.
