I don't see this as any worse than figuring out where nested parentheses are closed: tooling helps. I'm almost certain there's a whitespace plugin equivalent of Rainbow Parentheses for your IDE/editor of choice
Yes, tooling helps, though I am not always in my IDE. And I agree that it shouldn't be worse than, say, JSON, but for one reason or another my brain seems to struggle with it just a bit more. It certainly does not seem like an improvement, which I feel is implied.
