I'm tired of hearing the exact same arguments, "not needed", "just syntax sugar", "too much complexity", about every new syntax feature that gets added to JS. Somehow, once they are in the language, nobody's head explodes, and people are soon using them and they become uncontroversial.

If people really this new syntax will make it harder to code in JS, show some evidence. Produce a study on solving representative tasks in a version of the language with and without this feature, showing that it has negative effects on code quality and comprehension.

Presumably it's up to the change proposers to produce said study showing the opposite.
