Deprecation warnings are already in the current version, since November 
17:

This part of the Handbook refers to fetching source for -CURRENT or 
-STABLE.  We should not be suggesting CVS to new users who want to run 
development versions of FreeBSD.  It's a misdirection, like a 
Perldoc-esque "here's an example, but you should never, ever do this".

Existing CVS users already know how to use it, being existing and all. 
So the removal of CVS information from this chapter should not harm 
anyone already using it and should help by not steering newcomers to the 
wrong tool.
