So what? I personally am a fan of recursive descent parsing for most programming languages, and if it works with recursive descent, why would it be troubling that it's actually an LL(4) grammar?
Now it would only be troubling if the grammar itself is intended to be widely usable across different languages, say JSON or XML. A parser generator really shines because it can generate code to parse this grammar in multiple languages. For programming languages intended to be written by humans, I value things like good error reporting far more.
