Comment 1 for bug 912796

This is not a security vulnerability and FTP is not deprecated. FTP is still very useful as a means to transfer files to anonymous users (instead of just HTTP) See ftp://ftp.mozilla.org/pub/mozilla.org/firefox/releases/ for example.

On the other hand, I agree that SFTP should be discussed in the server guide. You're welcome to try writing a guide to setting up SFTP which could be included in the 12.04 edition.
