As a dev, I honestly can't understand that. I probably use regex a dozen times a day. Basic regex is so easy and useful, but describing exactly what you want is so iffy for an AI. The basics of regex are also so easy. It's not like most people are trying to, say, parse an email address with regex. Most usage is basic, like "extract this consistent pattern from this text" or "remove this (simple) parameter from this function". It takes me seconds to come up with a working regex in most cases.
