Why is there no warning that disabling an extension there will REMOVE IT (wiping your config) instead of just disabling it so you can restore it later?

You should either add a warning or offer the user a choice to remove or disable it temporarily. A lot of people doesn't backup their extension settings regularly so having an option like that with no warnings seems like a terrible idea to me.

Instead of showing a warning, we can simply split the current "toggled off" state to be different between "disabled" and "uninstalled". When the user toggles the button on an extension in brave://settings/extensions/v2, we should "disable" first, and then show a button called Remove next to the toggle. Then we don't need a warning.

Yup, that's very close to what I meant with:

or offer the user a choice to remove or disable it temporarily
