There is no way to autogenerate migrations that work in all cases. There are lots of things out there that can generate migrations that work for most simple cases.

They don't need to work in every case. For the past `~15 years 100% of the autogenerated migrations to generating tables, columns or column names I have made just work. and i have made thousands of migrations at this point.

The only thing to manually migrate are data migrations from one schema to the other.

Django manages to autogenerate migrations that work in the VAST majority of cases.

I end up needing to write a manual migration maybe once every other year in real world use.

That's why you can do your own migrations in Django for those edge cases.
