I love ardour, I wish only for native Wayland support.
But even if we do want to take this hurdle, is it even possible yet? What interfaces are available to do this on Wayland and embed a plugin-drawn GUI in a GTK 3, GTK 4, Qt 5 and/or Qt 6 application?
My guess is we still need a new spec that would probably revolve around OpenGL/EGL or Vulkan/WSI, but I'm not sure, and there's also the question of how input events are delivered.
