A Rails 7.1+ cop to suggest using normalizes

[Darhazer]

Is your feature request related to a problem? Please describe.

Rails 7.1 added normalizes that can replace before_validation callbacks that change an attribute
It would be nice if we can have a cop to help people upgrade their codebases

[Earlopain]

Can you provide some examples you have in mind? In a codebase I worked on we had plenty of before_validations that just initialized some field, without a specific guard like on: :create.

Not the greatest pattern. Basically some immutable model once created which means before_validations run only once while with normalizes that would also run for queries against it

Personally, I don't think this can be solved by a cop, except some of the simplest cases.
