I noticed that you can call e.g. LuaEntity.get+filter() or LuaEntity.get_or_create_control_behavior() on an entity ghost representing an inserter and it returns the information associated with it.

Is that intentional / officially supported or some undocumented behavior that might go away at any moment? The docs are unclear (they don't mention ghosts at all).

It is intended. Since 2.0 configuring ghosts has been expanded to cover as much of the mod API as we can without crashing.

Ghosts are mentioned at the top of the LuaEntity page:

Most functions on LuaEntity also work when the entity is contained in a ghost.
