I think that including a parser in the standard library is either too high a bar or too low a bar, depending on the scope of the language's standard library. Either way it's somewhat arbitrary. It would perhaps be better to say that a (language idiomatic) parser is available for the language that is maintained and used by the core language team and easily importable by third parties. That way you avoid the minimal vs. batteries included standard library philosophical arguments.
