No, we don’t “need” it. But how do you think progress is made? People come up with new techniques and tools all the time, based on their previous experiences with a platform.

Sometimes these projects wither and die. Sometimes they find niches where they’re particularly useful. Sometimes they hang around with a core of dedicated users. Sometimes the ideas they introduce go on to influence other languages. Those are all beneficial.

I’m surprised to see this same complaint levelled so often.
