@ Is this worth doing as a first cut implementation?
Probably not.
It looks as though the MirDisplayConfiguration based APIs are partially deprecated (there's missing functionality in the MirDisplayConfig APIs which would inhibit full deprecation).
It may be worth noting that the "nested" server configuration does something very like what has been suggested in comment #7 using the MirDisplayConfiguration based APIs. (There may be value in reworking that in parallel.)
