Comment (by loic):
Just to clarify the nature of the backwards incompatibility:
{{{
class BachelorParty(Model):
events = CustomManager()
class MessyBachelorParty(BachelorParty):
pass
}}}
`MessyBachelorParty.objects` wouldn't exist anymore, and
`MessyBachelorParty._default_manager` would be an instance of
`CustomManager`.
{{{
class BachelorParty(Model):
objects = CustomManager()
class MessyBachelorParty(BachelorParty):
pass
}}}
`MessyBachelorParty.objects` would become an instance of `CustomManager`
instead of just `models.Manager`.
