Use _typeshed.SupportsItems instead of custom _HasItems protocol.
Use a custom covariant protocol for mailbox messages.
Add Mailbox._dump_message.
Return a protocol from abstract method Mailbox.get_file().
Return concrete type BytesIO instead of typing.IO from Babyl.get_file().
Use our custom protocol instead of semi-protocol typing.IO in the remaining cases.
