@RAOF@dev.glitch.social Ordinarily I'd agree with you entirely, but you're attempting to propose a standard, which everyone has to abide by by definition or it isn't standard :-)
I think it'd be reasonable to define "the RAOF HTML subset", though. Especially since one could describe that in OWASP Sanitizer language as Sanitizers.FORMATTING + Sanitizers.BLOCKS + Sanitizers.LINKS + Sanitizers.STYLES, for example. And then say "everyone should be able to rely on RAOFHTML" and make a sanitiser for each language.
