Comment (by patrys):
It's also the case if your app does not have an `AppConfig` file and your
`INSTALLED_APPS` is a list of byte strings.
As I've noted in #25906, I'm not sure working around problems like this at
Django level is worth it. It will add a lot of seemingly no-op code that
in edge cases could silently cover entire classes of unrelated problems.
I think it would be a sane thing for Django to warn about things being the
wrong type and do nothing about it. Affected apps and projects will
continue to work in Python 2 and fail in Python 3 but they do that already
(they may not know or care). A warning should give enough information to
fix the problem (or file a bug with app's upstream).
I was affected and it took me a couple of months to find out. Our entire
test suite passed with flying colours and things only broke when squashing
migrations. With a proper validator warning it becomes a five minute fix.
