No one is arguing to roll your own when there a generic sort in the standard library. The issue with clever things is that people try to make a all purpose solution for what could be a simple one off solution. The all purpose is only used for 2-3 uses and it never battle tested.
I am not arguing for Go. I am arguing that there is an issue with some complex languages. Go is trying to avoid that issue. I agree that the issue is real but also think go takes it a little too far.
Haskell, if that's where the sneer is addressed to, absolutely gives you that.
It's just toy first-timer Haskell examples of quicksort (that still work, mind you) that don't.
But then again, take a language like C, and consider how many things (like proper error handling) are missing from 99% of the toy tutorial examples available.
