have the best say on and (2) voting on the alpha-ness / beta-ness may not be a productive
exercise in non-trivial number of cases (as I have seen with the release-level tags, some
users think an alpha release is of production quality enough for _their_ use-cases).

maybe discuss having a list @ release time. As an example, s3 and encryption at rest shipped
in beta stage... what's in 2.8 that "we don't yet trust ourselves?".  Me, I'd put erasure
coding in there just because I've no familiarity with it

up traversing (some if not all of) alpha features and making sure the corresponding APIs are
explicitly marked private or public unstable / evolving. I do think that there is a lot of
value in us  getting more systematic with this - how about we do this for the feature list
of 2.8 and evolve the process?

+ have people add JIRAs for the next version to actually mark things as stable/out of beta
