Comment:
Thanks for the report. You can create custom signals and send them from
anywhere, so I don't think any validation of a `sender` is feasible here.
When connecting the receivers,
we don't know if the code sending the signals is reachable. For example,
folks can send built-in signals from abstract models of their own, and
this will work fine. `pre_save`, `post_save`, `pre_delete`, and
`post_delete` signals connected to an abstract models will never be send
(without custom senders) because `save()` and `delete()` methods are not
called on abstract models. I'm afraid that any additional note in docs
will confuse folks even more, however I'd be happy to review your concrete
proposal.
