None of those could be implemented in JavaScript or WASM. XSLT could.

Say what you will about the popularity of each of them, but they can't exist without browser implementations. XSLT can be replaced with a polyfill.

Show me how a polyfill allows me to type https://example.com/rss.xml in the URL bar and have it transformed to HTML in the browser?

I don’t think I’ve ever wanted to read an RSS feed directly, although I subscribe to a lot of them. Is that a popular reading method?

It's a popular presentation format for RSS feeds. And you don't need to somehow attach a Javascript polyfill to an XML feed to make it readable for humans

i do that frequently, especially on podcast feeds where i am not actually interested in the rss entries but in the linked audio files. the rss reader doesn't play those well.

[em-bee]

how do you do that with anything else?

firefox doesn't load the file at all, but loads it into an external tool which (gasp!) is chrome. chrome displays the raw xml.
