In my opinion, providing the "no nesting" guarantee is more useful than
being consistent with XHR, if all new APIs provide it.

This sort of thing seems obviously useful:

function showActivity(obj)
    obj.addEventHandler("loadstart", function() { div.hidden = false; },
    obj.addEventHandler("loadend", function() { div.hidden = true; },

With the currently specced behavior, this doesn't work--the div would end up
hidden when it should be shown.  You shouldn't have to care how other code
is triggering reads to do something this simple.
