I will try and think about more of the issues here when I have a little
more time, but in the meantime I think it is worth noting that this
argument assumes that the same code is being executed by all web
browsers. Since it is common practice to differentiate code path based
on UA, it is quite possible that changing this behavior would have
serious compatibility implications for non-IE browsers despite the lack
of IE support.
