A fork six weeks old is a promise; a fork with a stable release and a governance model is a slightly larger promise.
what was actually checked, rather than assumed:
governance a foundation, with named member
organisations. real.
compatibility protocol-compatible with the version
we run. verified by pointing our
integration tests at it for a week.
packaging distribution packages exist; the
container image is official.
the client
libraries ours works unchanged. the one we do
not use has a fork of its own.
decision: still not migrating. but the option is real,
which it was not in March.
The difference between March and May is that the migration is now a boring afternoon rather than a bet, and that is worth establishing before it is needed rather than during. Running the integration suite against it for a week cost nothing and turned an assumption about compatibility into a measurement.
