{ is only special if it's followed by /\d+,?\d*}/. If they want to add anything else that can go between { }, they have to either add a simple rule to the language (always backslash { unless you want special behavior), or a bunch of weird rules that they might want to change again later.
} is never special unless a preceding { makes it so.
