I think it means that we should put on the suffix, per your proposal.
It makes it obvious that the rosdep keys *always* give you -dev
versions, so there are no surprises.

Yes. We'd probably want to normalize the ones used in the catkin-ized
stacks first, then pick our battles after.  There be dragons.

Probably not. That's definitely first freeze material and the sort of
thing that always bites us badly if we attempt to repackage this late.
