Comment:
Hello,
I tried to tackle this ticket as I believe it would still be a pretty
useful addition to `makemigrations`.
During development, I often see developers struggle with the manual steps
to re-generate a migration while they are still iterating on their
approach.
Here is the approach I've taken
https://github.com/django/django/pull/15669
I tried to keep the implementation rather straightforward.
The main drawback I see is that it will add a new edge case when one
updates a migration that has already been applied. This will create a bit
of confusion, as it will become more tedious to undo the updated
migration, since the reverse operations will try to undo things that
weren't initially applied.
