In Purism's latest Librem 5 blog post, they showed their prototype of a mobile-oriented Wayland compositor named Phosh. It may be useful on pmOS.
The code is at https://code.puri.sm/Librem5/phosh . I haven't looked at what dependencies it would need.
Note, @MartijnBraam has started work on this in the feature/phosh branch. dbcf1c32333673e3b02f05353e0afe08415d5e7d
However, the current problem is that GTK3 in the Alpine repos isn't built with Wayland support.
EDIT: Solved that problem. It all compiles, now we just have to get it running.
