I mean, does it? I was under the impression that it enforced double- or even triple- buffering, which is NOT what you want in "here is my output, put it on the display plz" situations. Maybe you are implying that they finally fixed that?... but, the fact that they tried to cram all this stuff down everyone's throats first before fixing obvious deficiencies--leading to a bunch of obsolete understandings over totally fair complaints about software a decade too early being constantly evangelized by asshats on forums saying you're dumb for still using X11 when Wayland was not even a half-baked solution--is extremely dumb.
Graphics-stack developers have known that in order to keep pace with Windows and macOS, X needed to be replaced, since the 90s at the latest. The only question was with what. The Xorg developers came up with a solution: Wayland. The hackers who wrote Xorg are in unanimous agreement that X is obsolete and you should be using Wayland instead. The next step, now ongoing, is to coordinate with DEs and distros to remove X support altogether.
You should use Wayland because it's what's supported. It's what all future Linux graphical software will be ported to. In a few years, it'll be impossible to get an X version of even a recent web browser. The best time to abandon X was 30 years ago. The second best time is now.
And yet, abandoning X for Wayland--not to start developing Wayland, but to actually stop using X and start using Wayland--is MUCH easier to do now than it was to do five years ago, despite all of the people (maybe including yourself) who were INSISTENT that you had to do it IMMEDIATELY or suffer some kind of consequence.
This is a similar situation to the people who were all screaming that you had to ditch Python 2 to upgrade to Python 3 immediately after it came out, and that if you didn't you were somehow dumb, even though they finally started to fix all of the upgrade deficiencies and regressions only with something around Python 3.5: there's a time to upgrade, and that time is never immediately upon introduction.
What people do not seem to get is that Wayland is what they wanted Xorg to be. A lot of what Wayland could not do were things they did not think it should do.
In some cases, the Wayland team has been dragged kicking to implement things. In other cases, they have stood firm and we will be leaving them behind.
The people that developed Wayland were the exact same people that developed X.Org. I'm sure they thought of all possible options because they are actually very smart people.
Well: 1) it isn't always the case that the people who develop a system in the center of an ecosystem are actually the people who know best how the entire ecosystem should work (and in fact there is an entire trope of second system effect destroying such a reboot); 2) it isn't at all obvious to me (and in fact it feels incredible to me) that the people who put most of the effort into X.Org decades ago are actually "the exact same people" who are in charge of maintaining it today; and 3) the specific thing we are talking about here has been discussed numerous times in the past decade by people developing low-latency and high-performance apps--such as games, which is where you really want to be able to get the display server out of the way--and was, in fact, known to introduce a ton of latency that they were going to figure out how to fix some day (a similar situation to how Wayland completely fucked up display scaling by forcing integer scaling, which required patching later and now is a wart in the architecture already).
