GPT-5.2 and GPT-5.3-Codex have been sunset in Codex with ChatGPT subscriptions

I’m a paying ChatGPT/Codex user and I relied on GPT-5.3-Codex for real development work. Removing it from Codex Desktop/CLI for ChatGPT accounts broke my workflow. GPT-5.4 and GPT-5.5 are not equivalent replacements for my use case: GPT-5.3-Codex handled long end-to-end repo analysis with much better token/credit efficiency, while the newer models burn through usage much faster. Please restore GPT-5.3-Codex as an optional selectable model, or provide a true low-cost Codex replacement with comparable coding reliability and token efficiency.
