Research direction

Start in Python's multiprocessing.managers module and inspect _BaseSetProxy's ABC registration, then check the related multiprocessing manager tests. Done means the set proxy is registered with the appropriate set semantics rather than collections.abc.MutableMapping; note that linked PR gh-142741 indicates the work may already be underway.
