I think maybe a simple policy like:
* always disable them for release builds
* require env vars to enable at runtime
would be enough to avoid having distros pick them up and block people from "relying" on them.
Otherwise Jason's comment on collaboration seems sufficient for doing updates to the headers/xml. Might just be something we work with a bit more ad-hoc as more people start to work on/with beta features too.
