There seems to be general confusion on what Wayland is and what it does.
Anyone who worked with X11 back in the R4 and R5 days probably understands
the issues with the client/server protocol. I remember all of the
optimizations needed to get it to perform even passably on VMS, most of
which went into R6. But the protocol is still painfully primitive and
awkward in today's world. It really has no concept of compositors and that
makes everything much more expensive on both the server and client sides. I
really expected something like Wayland to show up 15 or 20 years ago.
Putting Wayland into the system has a minimal cost in disk space. Unless
you choose to use it, it has no impact on application performance or size.
It mostly means that, if you want to use Wayland, you can o so without
rebuilding lots of stuff from ports. The packages will have be built with
ll of the required linkages. Does not matter what desktop you use, though
many of them may not yet work well (or at all) with Wayland, many will and
you wilol be able to try Wayland out easily.
YES!!! Wayland support should be present when available. It's all upside.
