I agree that one should push back, but I suspect we have different notions of when to do that (which is fine, my approach here is not fixed in stone). Making a page needlessly dynamic would be a concern for me if it violates business rules or for whatever reason harms the overall system. But if it doesn't do that, and it genuinely does make the business and users happy, then I'm happy to do it and then get a bit of leverage to take some time to tackle tech debt that needs addressing on the backend.
