The problem is that the Wayland fans have a tendency (at least I feel) to significantly misrepresent things in their favor. Statements like "oh that's actually more efficient on Wayland". No, Wayland is incapable of the sorts of optimizations X can do by design. It is only more efficient if the X app is doing things in a specific way that doesn't take advantage of huge parts of the X protocol. Granted, most modern apps do exactly that at this point. That doesn't make such statements any less of a misrepresentation though.

A much more reasonable claim would be that the network transparency afforded by the X protocol adds significant complexity which is no longer utilized by the majority of mainstream apps today. As such there's a reasonable case for dropping all that complexity from the core system and leaving it to peripheral libraries to handle on a case by case basis for the apps that want to make use of it.

And the idea of lossy compression while using an image editing program being a desirable thing (as suggested elsewhere in this comment chain) is laughable. It's already bad enough reading text that's gone through lossy compression. I would never want compression artifacts while manipulating an image.

My impression of Wayland so far is that I like the technicals but absolutely detest the people I encounter pushing it as a solution (it's quite similar to Rust in that regard I suppose). They would probably meet less resistance if they took more care not to misrepresent the overall state of things. I'll leave the link to KDE Wayland "showstoppers" for reference. Certainly that list is far shorter today than it used to be and many (not all) of the items are now solely on KDE's end. Nonetheless, fanboys have been claiming that Wayland is "production ready" the entire time. https://community.kde.org/Plasma/Wayland_Showstoppers

I'll switch to Wayland once it "just works" out of the box in terms of app integration on stable distributions including things like screen capture, fractional scaling factors, color management, all the stuff that works on X.
