I'd really like to discuss rethinking our forward-compatibility
policies, since we have (now) 3 active stable/ branches, plus head/. 

What I would like to see, with my RE hat on, is a "best effort"
backwards compatibility to being able to build the lowest-numbered
supported stable/ branch on head/.

Sure, this won't always work, but "best effort" is better than "no
effort", which the latter is why we do not have stable/8 snapshot
builds, to be honest.  I won't spend the time on the stable/8/release/
code nor the snapshot build scripts to waste the time.  Building
stable/9 on head/ is annoying alone.
