Obviously, I agree that micro releases would be good - but I understand
your position. All of this is hypothetical at this point anyway, since the
node adapter bits I care most about are not yet full citizens and we have a
little time to get all of our ducks in a row.

2) There is no change in the adapter between releases of Keycloak server.

Absolutely - I understand. We went through a lot of this soul searching
with WildFly Swarm recently, and ended up allowing for separate versioning
between "core" and "non-core" pieces of the project. There's not a lot of
data to go on yet, so we'll see how that turns out. But in this case,
wouldn't the most recent Keycloak server always just use the latest version
of a given adapter for any new release?
