Some alternative improvement proposal on the config.toml

What variant of Codex are you using?

App, CLI

What feature would you like to see?

I'd like to propose to add [overrides.<machine-name>.<config-key>] support to the config.toml. This will have a higher precedence over [<config-key>] in the config.toml if the <machine-name> matches the current machine. And we disallow <config-key> to be overrides.

This has these pros:

1. Allows config.toml sharing on multiple machine / multiple platforms.
2. Easy to reason about. Generic enough to cover other / future configs.
3. User can add machine depending config to it. Say, user can enable notification in macOS but not in headless VPS.
