Hi Sam, Thanks for asking the mailing list. This is a good example of where a courtesy note helps folks know what is going on, without restricting your experimental work. The registry is great but I can't be the only one that doesn't poll it too often.
+1 to what Dmitri said. The HTTP/3 PRIORITY_UPDATE frame went through some iteration and, since frame parsing errors lead to connection errors, it's good to have a few codepoints that allow iterating without needing to strongly coordinate. Cheers, Lucas
