not with what was communicated with todays roadmap update. Unity 7 will be
the default desktop until 14.04, we will then assess whether Unity 8 is
ready to become the default.

One obvious benefit that comes to mind is getting the stack for free and
not having to worry about maintenance. I do acknowledge that there are
other costs associated to that (adopting to Mir), but in our opinion, that
should be less than maintaining a GFX stack on your own. Canonical will
support the Mir stack going forward and we are offering help for upstreams
willing to adopt.

We are committed to not regress anybody in 14.04, the availability of
binary drivers is one major component to that

today, XMir is invoked by LightDM similar to other X session compositors, I
don't see a problem doing the same out of GDM. But I leave it to my team to
keep me honest here ;)

I did some research and apparently missed that, no offense intended

imho there is a difference between a chance of doing it and putting out a
roadmap and committing to do it, but I might be nitpicking ;)
