is this intended to be committed on this PR/is it an artifact of a branch that is yet to be rebased?

Yes, this is PVA support.

We set epics CA address lists via a .properties file, but as far as I could tell no such properties exist for PVA and env/system variables were the only way to configure this for PVA.

I also found the PVA support in CS-Studio a bit flaky especially on reconnection - would be curious if you find the same. If so it's probably something we need to look into...
