Is there any good reason for removing the distinctive behavior of an element that so many older websites use, even if it is considered a design faux pas? History should not be destroyed.
I agree that history should not be destroyed and in sites that have old pages with the blink tag it won't be. But I think its fine for the browser makers to remove old cruft. Especially in this case where the behavior can easily be replicated in Javascript.
