Description
When verbose name of model or field is changed or some validator added/removed this creates unnecessary migrations. These attributes are not related to database at all and this will create extra migrations which then need to rebuild the state every time when migrations are run on validations are processed.
This is extra overhead that potentially can slow all tasks related to migrations, and also extra noise in version control and also is very annoying. This state (verbose name, validators and potentially other attributes) is not needed for datamigrations also.
I saw people to complain about speed of the new migrations framework and I think that this can help at least a little.
This is not tested it's jut my hypothesis.
This is by design, see #22837 and the last paragraph in The Commands section in the documentation.
