users to be on alert when WordPress.org plugins change hands

And herein lies the problem. How does a typical end user from the backend of WordPress stay alerted to when a plugin disappears or changes hands outside of clicking a link to the Tavern to read about it? :) I think these situations are going to happen more often and underscore the need to at least alert plugin users that the plugin has disappeared or the owner has changed. Maybe something that is opt-in.
