We could PostHog Feature Flags on the default settings to check what users prefer. It is available on our posthog instance.

Will those work even if the user didn't opt-in for analytics? The code seems to suggest it does, but I'm not 100% sure.

Also, if we use those the users won't be able to change the enabled/disabled state unless we wrap the Posthog FF provider with some local based one and make the local one take precedence. AFAIK our Android code is not really prepared for that.

We will not do this. Follow up ticket soon.
