I'm not sure forcing beta software for a critical piece of a desktop to
unsuspecting users is a good trade-off. You'll get some testing, for
sure, but in the end you'll rather have pissed users on one side, and
power users who will quickly disable it on the other side.

I agree that you don't want an insecure X in the next LTS. I recognize
that you should not do an LTS without an "interim release" where the new
stack is the default. The problem is the MIR/LTS timing: it looks like
since the next LTS is logically on 14.04, then it must be a default in
13.10, for its first appearence, users be damned ("interim releases are
for power users anyway").

An alternative plan would be to make 14.10 the LTS. Then you can
introduce MIR as an option in 13.10, make it the default in 14.04,
before making it rock-solid and supportable for 5 years. Was that
considered ?
