With Wayland, the ecosystem of window managers will never be as rich, because a window manager has to implement too many things to be usable.
or, much better, use a compositor with a plugin system, so window managers can become plugins! :)
I've used it since its inception, however it has always kind of sucked.
I think it goes to it's basic philosophy: it did not enforce policy.
This let it survive a long time. It was whatever people wanted it to be. But because of this flexibility, it never became great.
It's like the old Lilly Tomlin skit - "I always wanted to be somebody, but now I realize I should have been more specific."
The sway compositor has been standardizing protocols for screenshots, screen recording/streaming, composable desktop components and so on.
