I disagree with you here.
I find that Xorg is really starting to show cracks as new hardware, and especially new inputs, are becoming mainstream.
In particular, I think Xorg does a crappy job with
- Audio in general (but bluetooth specifically)
- Gesture/touchpad input (some folks are trying to fund this still, but Wayland feels about as good as macOS by default - This was my "must have" feature that pushed me to wayland everywhere)
- HiDPI support - it's ok if you have the same resolution on every screen. If you're mixing resolutions, wayland is MILES better. Even XWayland is bad here - this is just truly a limitation of XOrg.
- Privacy. This one is a mixed blessing. XOrg lets apps do a lot of things to other apps. This is nice in some ways, because things like screen-recorders work easily and without permissions. But problematic because it means any app can quietly be a screen recorder.

Xorg still wins in terms of overall compatibility, and in user customization. But I think it's pretty clear from the statements from the Xorg & Wayland teams that Xorg is not just "mature" - it's in the process of being slowly replaced with system that most of them feel is better.
I think the more likely scenario is that you are not using the features that really make a distinction (which is a-ok!). In that case stick with what works for you. Xorg isn't going anywhere any time soon, and if your workflow is stable, you aren't missing the new stuff.
But other people absolutely are, and it's not because Xorg is "finished" - it's because it's broken and no longer getting the level of support it used to, that's mostly going to Wayland now (and it REALLY shows, if you use it for a while).
