The point I was making is that, for the 14.04 timeframe, nearly all (if not
all) desktop software we will care about supporting in the 14.04 LTS will
be X-using applications. This implies that XMir will need to be supported
for the support lifetime of 14.04 LTS itself.

I can't speculate how many releases /past/ 14.04 XMir will remain relevant
for Canonical, but I expect the community will have plenty of advanced
warning by which to make their own plans.
