+1 I fully agree: this zero-overlap plan will drastically delay adoption of
Indigo.

For example, the UTexas CS department will not be upgrading their student
computer labs to Trusty until August. They will remain on Precise until
then, so the Robotics lab will continue using Hydro on Precise. So, no
substantial work with Indigo will happen before the fall session. At that
point I don't know what will happen; with no concurrent platform for Indigo
migration, we may be looking at a train wreck.

We never had to cope with that sort of abrupt discontinuity in previous ROS
distros.
