What would be the reason to remove references to old Emacs versions
from the FAQ?  I'm thinking maybe we should simply exempt the FAQ from
this process, which is, of course, perfectly valid for the other
documentation.

The FAQ is supposed to be a place where people could look for
information like "since when does Emacs do this-and-that?".
