Listen, upfront, I don't give so much as a rat's ass what you use, if it works for you. I personally use X11 since that's what works for me, but I personally have no objection to Wayland.
That said, I'm excited for a potential resurgence in X11's development, but I feel XLibre isn't quite the way to go. In the 3 or so weeks it's been out, Enrico Weigelt (the lead dev) has made it clear that he doesn't really care to test for bugs or keep the project compatible with Xorg. Couple that with the over-politicization of the project (why politics should matter in a software project as innocuous as an Xorg fork, of all things, I'll never understand), and I'm hesitant to give it a try.
Simply put, the project holds no weight, in my eyes, as a valid replacement for Xorg, at least not yet. I think that with a restructuring in the form of dropping the politics and focusing solely on making good, stable, COMPATIBLE software, it could serve as a solid replacement.
But I feel that will not happen. In any event, if there's something positive to come from this, it's that Xorg, in response, has picked up development and seen new contributors who'd rather not associate with XLibre and all its buggy political nonsense.
I'm not gonna immediately turn my nose up at the project right now, but I feel it's not quite there. Like I said, it could be a solid Xorg replacement if it shifts its focus less on inflammatory politics and more on developing better software. I've been watching a thread over on the LinuxQuestions forum regarding the possibility of putting XLibre in Slackware, but Patrick Volkerding, the distro BDFL, shut that down pretty quick (a sensible approach in my book, hence why I love Slackware). I may spin up an Artix VM just to see what the hype's about.
This is just my two cents, and you're free to disagree. If you do, please keep replies civil - I don't care to hear about why "Enrico is so based and redpilled" or why "Enrico is the literal devil." Just don't.
That's my opinion.
