The Sunset HTTP Header Field
I'm aware that the following is typical HN middlebrow matter, but I'm asking anyway. Does anyone know why RFCs are still formatted as if they were written on a typewriter in the seventies? I mean, here's a sentence quoted verbatim from this document:    Sunset header fields will be served as soon as the sunset date is

    RFC 8594                        Sunset  Header                    May 2019

    less than some given period of time.

What problem does this solve? How is this more useful than it is cumbersome? also, how do people write this? Do they manually space space space space align the footer and then copy it every 30 or so lines?
