I agree that "ftp://" is entirely different from "ftp.wikipedia.org". But I still don't think that we should abandon stability because a Web site, even Wikipedia, chooses to mix ISO 639 IDs in the same distribution position with "www" and "ftp" as sub-domain names. If ISO 3166 were to go changing their IDs (alpha 2 or alpha 3) for such reasons, we would rightly criticize them for not being stable. Same with other standards.

ftp:// is entirely different from ftp.wikipedia.org
www:// is meaningless in every context.
