I'd gladly accept if my daily browser traded some backwards compatibility for speed, security and the ability to move forward faster.

Obviously only if I'd be certain some other browser can still open it, or maybe some emulator would be able to display it. My earliest websites are 27 years old now (and live on a floppy disk) I'D hate to find that they're no longer readable in any software.

But I'm perfectly fine with my Firefox, with which I spend hours a day on the modern web, dropping support for that, when they need to shed some cruft or weight.
