: I guess this would generate a lot of stupid questions on mailing lists

Which happens already.  Am guessing concerns are really more a matter of:
1) NetBSD distributes (readonly) CVS via ssh or pserver (and NetBSD has for a
 long time distributed a version of ssh)
2) developers (on distributed projects) use CVS over ssh mostly
  (NB. you'd hope that developers generally can set env. vars.)
3) segregated networks may use rsh (maybe libwrap'ed rsh) but they're also
 more likely to delay or fully compensate for changes in base utilities
4) the change is so obtrusive that people would be severely inconvenienced
 by such a change in development environment - consider the main idea being
 that people who use CVS have a good base knowledge of systems and tools of
 those systems

I'm suspect (without validation) that itojun's idea is that point 3 is so
rare that those people are fully taken care of and that anyone else can
cope with such a change (which conforms with most common practice (I think))
