Comment (by Seth Syberg):

 One point of clarification on the `Autodetector` suggestion - I'm running
 `makemigrations` on an empty database and no `initial` migrations at all.
 It's as if I just coded all of my models at once and ran `makemigrations`
 for the first time. In theory this should always work right? Especially
 given that this is live production code and there exists a set of
 migrations that can be run successfully to create this database state.

 I'm open to trying to produce a minimal reproduction, but I have no idea
 where to even begin. This only cropped up after we'd created 7+ apps with
 100s of models. I think if I knew how to create a minimal reproduction,
 I'd also know what to comment out to create an `initial` migration and
 wouldn't be submitting this ticket at all.
