This is something that I am sure will be solved eventually, but one of the major weaknesses of Wayland is the lack of lightweight standalone compositors.
For example, if I want a lightweight stacking window manager on X, I can choose between Openbox, Fluxbox, FVWM, IceWM, Pekwm, JWM, Window Maker, hell even twm if I were a masochist. I have tried out all of these at one point or another and they all have something to offer users. But using Wayland, there's, uhh, labwc, and that's it? Maybe I could try using kwin standalone?
The situation for tiling window managers is similar, with Sway being the only one that feels mature.
I plan on migrating from Openbox to labwc at some point in the future, once it's ready. labwc itself is really good, but some of the other programs I need to recreate my setup aren't there yet. Someday...
