pre-WWW URLs, other URIs?

[dchmelik]

Is this the main place to make suggestions on (GitHub-flavoured) markdown? If so (otherwise ignore), seems markdown only does WWW URLs, not pre-WWW Internet technology URLs, other URIs (URL is type of URI)... major ones are email (dating to 1962) which uses imap, mailto, pop, smtp URIs (still common), (and others dating to '69 to '71 include) telnet (not large percentage, but maybe almost 1,000+ known left, and used on local area networks, various common network/service debugging), (s)news/nntp, ftp (still-used, dying due to misunderstanding of major web browser younger computer programmers/scientists (CS)), finger ('77, irc(s) ('88), gopher. IRC (with finger) & NNTP (maybe even gopher) are still much more popular than one might think (besides generation x & older scientists/programmers whose first Internet service providers typically educated them on all this, unlike irresponsible major corporations), so can you please add these major ones? Of course, URIs usually run on one or more of 65,5536 Internet protocol ports (some unused), so there's a growing number. Obscure (but sometimes more-used) and new major ones are bluetooth, chrome/etc., content(-type), dict, dns, fido, file, ham, gemini, im/etc., magnet, maps, matrix, moz, ms*, nfs, proxy, sftp, smb, tel, udp, wifi, many related to science/programming & version control systems (VCS), general system administration & networking, money/cryptocurrencies, and other things. Internet Assigned Numbers Authority's list isn't exhaustive (check similar & CS sources, Wikipedia): URI Schemes. In theory all (except 100% discontinued services such as gtalk, msnim) should be added.
