Comment (by Tobias Kunze):
> This is not a bug!
Could you elaborate on this? As it is changed behaviour from Django 2.1
and previous versions, it's either a bug/regression, or a documentation
bug by not mentioning this changed behaviour in the release notes, in my
opinion. Up until now I've assumed that `something.related.count()` and
`something.related.all().count()` will yield the same result, and if this
is not true, it should be documented. (Or is it documented? Could you
point me at the right place to look?)
