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

I certainly did not expect it. I think this takes the cake for the craziest AI company move (yet) that impacts my daily workflow. 5.5 is so much less efficient than 5.3 codex is. just taking it away, no notice, no nothing, no replacement so I gotta google whats going on with a subscription I pay for. wild.
