Thanks for the bug report. This feature is no longer experimental, so it has been removed from the experimental menu. I'll update the tip to remove the now-inaccurate "Disable in /experimental."

There's no "none" option in personality tab either, I had to manually do it via config... or am I actually doing nothing and just defaulting it to pragmatic?

Just noting the "None" option promised by the linked post is neither present in codex-cli nor the codex app as of the latest version on April 27th. Also, did you guys rerun all of the coding-related benchmarks in the GPT-5.5 announcement blog using both personality prompts to ensure all of the instructions there don't negatively affect performance?

Yes, we ended up removing "none" as an option. It wasn't needed for the reasons explained in the linked post.
