It is, including the author of this post. Unlike other controversial things like systemd or pulseaudio, Wayland was started by major Xorg contributors. I've watched some of their talks and can see why they went down this route.
I've tired Wayland a few times and whenever I do, I give it an honest shot for a few weeks, but tend to run into issues (Sway being pretty buggy or oddities with old X apps or Steam, etc.) I've heard Sway has gotten a lot better and I should really try it out again; probably the next time I setup a laptop.
I do wonder what plans FreeBSD and OpenBSD have for the future. Currently they main their own Xorg trees, but I wonder if we'll ever see Wayland implemented on other platforms.
I used Sway during the 0.14 cycle and ran into some issues e.g. with pointer warping in X-based games, so I decided to wait until 1.x. I just switched to Sway again, with 1.1.2 AFAIR, and mostly everything is working smoothly for me this time around, including Minecraft. :)
Things that don't work for me:
- mirroring (i.e. two displays showing the same windows at once), but AFAIK this is being worked on
- KDE Connect (not Sway's fault, but not having this working really hurts sometimes and might just make me go back to Plasma)
My understanding is that Wayland was started by a few core developers of Xorg who just couldn't stand maintaining Xorg anymore.
