Technically there's nothing wrong with it. That's the problem. These "gotcha" takes that some random language from 20 years ago already had feature x so talking about it now makes no sense are as common as they're misguided. A simple example is Go's autoformatter `goftmt`. In my opinion an earth-shattering invention. But to see that you need to go a bit beyond the basic, binary thinking that only true novelty has any value. There's a fundamental difference between a language like Python that has 2-3 competing autoformatters used by <5% of Python programmers [1] and Go's single autoformatter used by >95% of Go programmers. Technically Python and Go are equivalent here, but in reality the gap between them is enormous. That's why pointing out that feature x has existed since the 70's or that every other language has x too isn't a useful insight. [1]: I'm of course talking about the state of Python and Go around the time Go was released.
