Yes, but the specific problem is that it's not general knowledge exactly why you shouldn't attempt it. Ask a handful of developers and see how many mention Chomsky Type 3 grammar, or even regular grammar. And unless you scope an understanding of what regexes are to that, which is non-trivial, you get some bizarre feature requests, because people are attempting to use it inappropriately. They don't know what they don't know.
