I understand that. And I still think these changes might be particularly expensive ones. Trying to keep track of what workarounds you do and do not need to use is hard. Removing workarounds is good, but still an expensive step. Applying a large set of rules can be quite easy after an adaptation period, but changing those rules remains hard. Even if the new rules are simpler. I'm not saying Rust shouldn't be making these changes. I'm just saying I think this might be part of the reason why you hear comments about how hard it is to keep up with Rust.
