There's whole classes of software that just don't make sense on Wayland. Most DAWs won't work because the whole point of a DAW is "be a big box that hosts docked windows of out-of-process audio plugins" which just isn't a concept Wayland has; the only way it would work would be to have Reaper or Ardour or whatever be its own compositor. Maybe somebody some day will write a "libsubcompositor" or something; IDK.
