The heuristic isn't the problem. The problem is that we have no
technology that allows us to handle the complicated case of multiple
displays, and solving it purely for the simple case makes the
complicated case *worse*. Adding additional complexity for what would
be, at best, a different set of problems doesn't seem like a worthwhile
way to spend time. The only people who are actively upset by the status
quo are the ones who have the ability to fix it for their case, anyway.
