5.3 Codex disappeared from VS Code codex extension model options, expected?

Just wonder if this is expected? As I’ve been using 5.3 Codex even after 5.4 and 5.5 got released. I personally find it gives me the best outcome, for me even better experience than gpt 5.5. If expected, are we going to get any more codex models or going forward only generic gpt models only?
