> Every feature of every part of the HTML spec has to be supported for every transport. End of discussion. Where does that feeling of entitlement come from? What makes you think you have the right to access my camera or microphone via your web page, or even execute arbitrary JS on my computer in the first place? Websites have no right to do such things. They are privileges that I grant on a case-by-case basis via my user-agent and various plugins. You don't even have any guarantee that your DOM and CSS will render as you intended, because I block all sorts of things and sometimes even tweak the styles to make the content more readable. My computer, my rules. So I see no problem with restricting websites to a known-to-be-safe subset of features by default, until and unless a website can demonstrate that they take my privacy and security seriously. Privileges must be earned, not taken for granted, and ruthlessly revoked at the first sign of misuse. The HTML spec describes the maximum privileges that a website can hope to have, not the minimum that it can expect to have. If your website doesn't need any special privileges, feel free to use whatever transport you want.
