Unify max_length for EmailValidator and model's and form's EmailField

[jecarr]

As per this discussion, there is consideration to make the max_length values the same for EmailValidator and EmailField

[Natalia Bidart]

Accepting following ticket:34961#comment:9, where it's suggested that we should unify max_length to be 254 across the EmailValidator and the form's and model's EmailField.
But before moving forward, I would like us to understand the implications of reducing the max_length for the validator and form field, and evaluate whether a deprecation warning/process is needed.

I think we should make an analysis about how existing code bases could be affected by this change. Ideally we would describe how different combinations of using model's and form's EmailField would interact with each other when the max_length changes, considering both ModelForms and Forms. jecarr would you be interested in pushing this forward?

Replying to Natalia Bidart:

jecarr would you be interested in pushing this forward?

Thanks Natalia, happy to do so whilst going with your direction on this. Should I start by creating test cases to analyse the different combinations you outlined?

The ticket has already been claimed with a ​PR.

Sure, ok - when I wrote my previous comment the PR wasn't linked. I'll leave it to Kushagra S and happy to help if needed.
