As if oligopolization of the browser space wasn't a deliberate objective of the WHATWG.

I would rather have them deprecate the HTML syntax, which is a nightmare to parse, nightmare to escape for ( https://sirre.al/2025/08/06/safe-json-in-script-tags-how-not... ), and nightmare to securely transform (CVE-2020-26870). Now that MSIE is dead, all mainstream browsers support XHTML just fine; compared to HTML, XML is much, much simpler to make a new implementation of; and few people generate markup by printf any more.
