Python is actually full of limitations imposed by the indentation nonsense. Those limitations show up when a programmer goes beyond simple programs and wants to do more advanced things in the language. For example, lambdas are limited to one expression in Python. There's literally no reason other than because the indentation rules would cause problems otherwise.
So someone who wonders about C++ braces is someone who doesn't appreciate what advantage they provide. Such people don't appreciate the advantages because they haven't needed them in Python. They haven't needed them because they don't exercise the language fully. In other words, they are novice programmers.
I don't think we should care what novice programmers have to say. How about they just shut up and learn?
