I missed this IPv6 report from 2022 showing that most of the internet fails to handle various completely valid IPv6 packets that set some extension flags in the headers

@feld I was hoping that article would mention protocol ossification [1] and RFC8701 [2] GREASE ( Generate Random Extensions And Sustain Extensibility )
