Problem is, the IETF isn't really big enough to have a good idea about whether some technologies are still used. Example: A few years ago I started doing some work in an industry which makes extensive use of 3-way FTP, because they have very large files that they have to move around, and they need for those transfers to be mediated by 3rd parties. IIRC, the prevailing view in the IETF ftpext working group was that 3-way FTP was obsolete and should be deprecated due to security issues and because it wouldn't work through NATs.
