> VisualEditor and other editing tools would continue to support ISBN/RFC/PMID "magic" links as they do, but convert it to a proper link client-side.
@Legoktm: I thought the entire point of this was to stop doing magic linking. Why would we continue it in VisualEditor? When I type "RFC 2" in an article, I never ever want that to link to ietf.org, not in the WikiText editor, not in the VisualEditor, nowhere. Why would we want to still have such magical behavior in the VisualEditor?
