You've moved the goal posts quite a bit from your previous post to this one. Originally, you said that "progress is often only possible by breaking things... it's the only way forward". But the Ruby example that cortesoft provided isn't necessary to make progress. The language would get by just fine without that deprecation (or even without making the change at all). Saying "but it's a trivial change" in response is irrelevant, because you weren't originally trying to justify changes on the basis that they were easy, but that they were necessary.

Of course it's relevant. It's a laughably trivial example compared to the other one in this thread.
