I do not find adding another vector for problems, including malicious ones in the face of persistently broken sandboxes, to be "better". If it's a "page" I am going to "read", I don't feel the need to enable arbitrary execution of whatever gets stuffed down the pipe, beyond rendering the more restrictively defined HTML and some hopefully well-debugged -- although even with them problems continue to crop up -- image formats. It's like a biological viral infection. Hygiene can keep it out, but once it's inside, you may have a very persistent and possibly quite debilitating problem. I don't want to be disconnected from the world. Neither, however, do I want to engage in, um... "unprotected casual browsing".
