What we have now is really confusing and increasingly indefensible.
Also need to figure out some way to get at all nodes as well, maybe with a different route, an additional query parameter, or an 'all_nodes' entity.
In the PE HA docs we have the user do this manually, with the appropriate condition in PQL; we should remove that, since it's no longer needed. We should take a look for other such cases as well.
(the orchestrator may be doing this in its query munging code)
PQL queries and structured queries issued to the root query endpoint now automatically exclude deactivated and expired nodes. This has always been the case for all other query endpoints, and is nearly always what you want.
