> X HAS those things. Ubuntu's version of Gnome for example has supported fractional DPI scaling and per monitor scaling on X11 since I think 20.04. […] Xrandr has made this possible for years with some setup.
Via some ugly hacks that degrade performance and make things look blurry. It‘s not the same.
I mentioned network transparency in another comment, and wayland will never have that unless they implement that "degrade performances and make things look blurry".
So meh, you give and you take, life is a compromise.
If you have known the structure of the Wayland protocol before making the comment, you'd know that "official support" is a red herring.
The only official thing provided by the Wayland project (other than the protocols themselves described in XML) is the wayland-server and wayland-client library pair, which is more or less just a serializer and deserializer of the protocol.
There is also Weston, but we don't talk about it.
Waypipe is about as official as Kwin, Mutter or wlroots, and yet we don't disregard those projects as being irrelevant due to their unofficial status.
There are maybe five people in the world that care about network transparency (an exaggeration, but probably not more than 2 magnitudes of order off). X11 was built for every scenario conceivable. Wayland is being built for end-user thick devices. What you decide not to do is more important than what you decide to do.
And some dedicated soul managed to get it working anyway, as a sibling comment has pointed out.
