While Wayland is now available in FreeBSD (using a similar stack, with
libdrm + Mesa), AFAIU there is no support for DMA-BUF there because that
is Linux-specific. We may want to keep the nested compositor support for
systems where Wayland runs but are not Linux-based. I have no idea what
the situation is for the other BSDs, though.

As a reminder: Wayland is only communications protocol, just a peculiar
one with a very specific purpose (pushing pixels around, that is), and
there is not nothing to the its base protocols which is Linux-specific.
