I agree about workers, while webworkers probably won't work since destroyed while page is reloaded , it makes sense to check other workers if they are suitable to maintain PeerConnection or DataChannel in background between page reloads on the same website.

It is also true that many of the issues we've previously had to work around have disappeared with newer browser versions. That being said, some issues remain. The following are common issues / requests we get from our users that we feel must be addressed by the browser. (Either by spec or just browser implementations):
