Should we contemplate including it in the rule template as well? Otherwise, there's a chance we might overlook this aspect when creating new rules.

Alternatively, we could explore the option of implementing a script to automatically apply/remove this item (and potentially others in the future) to/from all rules.

I agree that it would be good to auto-inject this kind of things (we had case in the past with an assumption when Language is an input aspect) 🤔

Sorry, I thought I had marked it as "request changes," but I never started the review. Please refer to my previous comment.
