Why remove the Users search tab if ProfilePlus doesn't search emails?

ProfilePlus does a great job searching profile, as well as searching usernames. For my implementation, it's annoying that we've concurrently (and confusingly) lost the ability to search emails as well (especially given change to template to remove Users search tab).

Is the ability to search emails an anathema to the concept of ProfilePlus, or would this simple change be welcomed? I'd be happy to contribute the code...

Basic strategy would be to add a query for user->mail == entered string....
