This is true.

I don't really think that providing rendering libraries would make a
whole lot of sense for existing scene graphs. But it would make sense
for other window managers which don't currently provide any kind of
compositing story at all.

Perhaps this is worth doing some prototyping around to see what does
and does not make sense to split out? I'll put my hand up to
volunteer, but my time is pretty limited these days so I'm not so sure
how much I will be able to put into it.
