I'm not sure about whole functionality removed without replacement... 
You wrote to Tab "the legitimate use-case for popup windows is also 
reasonable, yet browsers have popup blockers." sure, but this 
functionality was not removed, etc... I can imagine no DOM/browsing 
context manipulation (even new browsing context) by default, only on opt 
in (but when the optin? before the beforeunload :) ?) But disabling it 
altogethe, because someone may alert "Do you really want to exit this 
page?"?
