vtk9 opened a new issue, #44909: URL: https://github.com/apache/arrow/issues/44909
### Describe the bug, including details regarding any error messages, version, and platform. For example, `_flight.ServerAuthSender` is not exposed in `pyarrow.flight` So we cannot write ``` import pyarrow.flight as flight def authenticate(self, outgoing: flight.ServerAuthSender, incoming: flight.ServerAuthReader): pass ``` without the IDE/linter erroring out that ServerAuthSender is not a known member of module `flight` There's also no documentation for it in https://arrow.apache.org/docs/python/generated/pyarrow.flight.ServerAuthHandler.html ### Component(s) FlightRPC, Python -- This is an automated message from the Apache Git Service.
