You might give https://github.com/juven/maven-bash-completion a shot. I
just tried it but it gave me some error. Not sure why. Bash code is so
ugly... .

Right. As said, #1 seems  to me best served by -pl {module}. I don't think
a custom option would be easier to memorize.

"mvn clean install" shouldn't actually fail without further ado atm.

For MongoDB we use the embedded DB if no external host name is configured
and CouchDB is skipped altogether.

Davide and I discussed to still compile and package the module and only
omit the tests (but display a warning). That way one would get the "it
works" experience out of the box and we'd actually have included everything
by default except the Couch tests. On CI of course the host name is set so
the Couch tests run there.
