That, I agree with, excepting fetching src/base for the buildworld;makeworld dance.

cvsup for base/src does not even have an end-of-life date yet, and the replacements are either:

- not clear
- not finished
- complex, confused, and difficult for systems integrators
  (people who buildworld/buildkernel as the stable base underneath everything)

For developers, I can agree that cvsup is totally the wrong tool.
Yet, that information should maybe be in the developers handbook, perhaps in the "tools" section:
http://www.freebsd.org/doc/en_US.ISO8859-1/books/developers-handbook/tools.html

(If yall' think that's a good idea, I'll happily write up a page to start with)

Oh, I see your perspective, but FreeBSD systems administrators are well accustomed to running -CURRENT and -STABLE, along with -REL and -RELENG, in production.

Here's some circumstances admins may build STABLE:
- Prepping an environment for upcoming releases
- Providing QA/bugs back to FreeBSD *before* REL goes out the door
- STABLE may contain a necessary bugfix, security fix, or other necessary feature in a given environment

Here's some circumstances admins may build a given moment of CURRENT:
- All the same issues from STABLE could warrant some point of CURRENT
- some existing code may need to be manually backported quickly in an emergency
  (I've done my fair share of "grep hacking" to solve crisis situations as an SA)

I hope that's understood?

Best,
