I agree in principle, however when we only have major and bugfix versions
something like this introduces another pressure to churn the major version
number.

I'm not generally one to worry about running out of numbers, but I do worry
about giving our users versioning fatigue. I also worry about the
maintenance overhead for devs; we still don't have any lifecycle plan for
major versions.

All-in-all, I think this comes back to the deeper discussion about what we
intend version number changes in Accumulo to signal. This general topic has
come up a few times, and we should probably get to a point where we have it
resolved.

Is now a good time for that discussion? Does it need to wait until
post-1.6.0?
