I have a weak preference for this logic to be somewhere in extension service,
like extension_service->DeleteProfile(), but even better would be for this step
to be a notification with ExtensionService listening to it (TODO other code in
here, do this too).

I'll defer to the profile/ owners for what they prefer, though.
