Disregard my previous post, I figured it out - here is a pure #Wayland desktop running on #Android, with a #Pipewire backend that is then being read by #GStreamer in a proot, which is then read by GStreamer on the host device through a FIFO (as raw YUV420 frames). It works, and all without X!

If you are looking for a tool to let you benchmark your PipeWire pipelines, test things during development or realitime performance graphs then maybe coppwr is the PipeWire tool you been looking for, check it out on Flathub:
