Comment:

 Managers were never intended to be accessible on model instances, we even
 
[https://github.com/django/django/blob/30d110ef43d8a3c50ea8ec4e4fe49bd2bb859530/django/db/models/manager.py#L186
 use a descriptor to prevent that usage] but  `_default_manager` somehow
 escaped that restriction. I guess we can mention the change in the release
 notes.

 For completeness I'll mention that if we really wanted these available on
 the instance we could just move the properties from `ModelBase` to
 `models.Model`, but I don't think we should.
