The Wayland API itself also really sucks to work with, even more so than Xlib....
But, RGFW's Wayland support will probably be improved in the future. :)

I'd also look at the work done on minimal wayland projects like [foot](https://codeberg.org/dnkl/foot), which supports wayland well and seems to be written by hand (see: https://codeberg.org/dnkl/foot/src/branch/master/wayland.c)
..an image decoding library.
..an audio input/output library.
..a multi-channel audio mixer.
..ttf and rtf font rendering.
..networking.
..runtime shader cross-compilation
..its own entire graphics abstraction layer / API.
..its own shader language, shader compiler, and shader bytecode format.
I don't know at which point something becomes 'high level', but SDL is only 'minimal' if you use a subset of its functionality.
(They may be good alternatives for certain use-cases)
GLFW's codebase is ~10MB while RGFW's is about ~300kb. But RGFW tries to support nearly everything that GLFW supports.
Are there any good minimal windowing utilities that support Wayland? SDL does a lot I don't need and I try to maintain minimal dependencies. I suppose I could just use glfw & libsoundio, haven't tried that yet.
