My opinion is exactly what Daniel said.

End users do not choose or use Wayland. End users choose and use a desktop
environment. How that desktop environment works under the hood is irrelevant to
the user.

Desktop environments can use Wayland as a branding name, like GNOME Wayland,
but it's still a flavour of GNOME.

All that said, you can make an educated guess based on the globals advertised
through wl_registry. 'weston-info' is a tool that lists them, works on any
Wayland server. A much more reliable method would be to use 'ps' to see what
processes are running, if you cannot find an "About" button on your desktop.

If your idea was to help debugging problems, then that too is specific to the
desktop environment and distribution you are running.

Furthermore, I would also argue that identifying the Wayland server via
protocol is actively harmful. It promotes adding server bug workarounds in
applications instead of reporting and fixing the real problem, and it bypasses
the intended feature discovery mechanisms.
