Data point: I run a site where users submit a record. There was a request months ago to allow users to edit the record after submitting. I put it off because while it's an established pattern it touches a lot of things and I found it annoying busy work and thus low priority. So then gpt5-codex came out and allowed me to use it in codex cli with my existing member account. I asked it to support edit for that feature all the way through the backend with a pleasing UI that fit my theme. It one-shotted it in about ten minutes. I asked for one UI adjustment that I decided I liked better, another five minutes, and I reviewed and released it to prod within an hour. So, you know, months versus an hour.
