Back-revving CVS in this manner isn't usually a concern.  Owners of
repositories can specify the minimum rev level of the client to use.
I would never dream of successfully using CVS v1.3 to access a
repository that's been maintained by CVS v1.10 or newer for any length
of time, and I don't believe anyone expects this arrange to work even
if local mode were permitted.

Breaking compatibility so that new versions of CVS become incompatible
with old repositories is of much greater concern, and rightfully so.
