sometimes it moves the complexity up the developer's head : "are you sure you really need to do all this, and there isn't a conceptually simpler solution to your specific problem ? Think again !"

That's the real value of "simple" languages like go.

“Am I really sure I want to loop over batches instead of fetching one record at a time (or the whole set of results at once)? Ugh, it’s a complete pain in the ass though, one at a time it is.”

You literally don’t have to use iterators if you don’t need them. You can just range over a collection as you do already. But when you want something a bit more performant like looping individually over batches or generating an enormous sequence of records on the fly, they make what would either be tedious or difficult into something trivial.

Go being “simple” just makes application code unnecessarily verbose and makes dealing with even moderately complicated problem domains feel like solving novel computer science problems when it’s be four lines of boring code in better languages.
