THANKS for all the analysis and details!  indeed let's keep them
separate then ;)

sorry -- myself haven't used that one yet and didn't dig too deep inside
for it.  IMHO it would be ok to upload in whatever usable build state

probably just  xserver-xorg-core  since xserver-xorg pulls too
much in.  I wonder if there is some obscure use-case where no actual
xorg server would be necessary somehow thus may be listing it in
Recommends

object! ;)  let's depend (or recommend) -core?
