It's partially redundant, but only partially, and I agree that it'll
probably be easier for people to use than the catversion number.

The case where it's not redundant would be if an add-on needs to deal
with an internal API change made in a sub-release, e.g. 8.1.4, where
the catversion number is not going to change.  We've certainly done that
before and will do so again, when there's no other way to fix a bug.
