I'm not sure if historically browsers were often taking the liberty of crippling widely used features in this way. We didn't kill marquee, for instance. For another example, I know that a lot of users dislike animated GIFs, and yet we haven't removed support for those.

How far would you be willing to go in forcefully improving user experience? We could refuse to render dark backgrounds to make text more readable, for instance.
