Re: [whatwg/fetch] Accept headers in spec cause confusion (#274)

This sounds like a good approach to me. Most implementations are pretty well-aligned in what is "ubiquitous", I think. Personally, I think only the following types have varying support in browsers (especially when it comes to top-level navigation):
- image/avif
- image/jxl
- image/webp (maybe?)
- video/x-matroska
- video/webm (maybe?)

AFAIK types like png, jpg, gif, mp4, avi, ogg, aac, flac have full support everywhere, but please correct me if I'm wrong. If `webp` and `webm` are considered ubiquitous then the amount of header size increase is even less. Media/image support does not change often and adoption tends to be slow, warranting at least some time where explicit `Accept:` entries are added.
