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.
