i do have some sympathy to the author's point but this strikes me as overly conservative. e.g. iframes have a lot of genuinely good use cases in being a completely seperate unit. e.g. try doing something like codepen without iframes. embedded widgets that need some sort of backend or a form that needs to be seperated from user-supplied html. i'm also appreciative of things like e.g. webcam support and webrtc, since it means i don't have to run proprietary always-on applications on my actual operating system, which don't have to ask permission for anything. and some are also just weird. favicon svg support? why do you care if favicons support one additional image format? should we get rid of jpg as well? maybe only use bmp for everything, then we can simplify things further and not have to include any complicated decoders in the browser
