At some point things have to stop being called "syntax changes". Just because you can represent the same operation by pressing more keys doesn't mean that it's not useful to add an abstraction on top of it to ease cognitive load, otherwise we'd all be programming with switches.

I think a better argument would have been that adding something that appears to just be a shorthand for writing functions is a potential footgun to language newcomers, but I think that argument is still relatively weak.

Then lets "abstract" your first sentience:

At point have stop called . Just you represent same by more doesn't that not to an on of to cognitive , otherwise all programming switches.

My point is, removing "function" and "return" from the syntax, won't necessary easy cognitive load, at least not for senior JavaScript coders. It will save bandwidth though! :P
