The RCS file format also provides a way to extend the format without
breaking compatibility, both at the file and version levels.  Naming
conventions can provide a measure of protection from collisions in the
event that RCS files are shared between multiple version control systems
that both make extensions.

And since CVS writes the RCS files directly (i.e. without the benefit
of the RCS executables), it should not be difficult to add such extensions.
