I am given to understand that WebCVS and ViewCVS can run 'rcs' commands
like rlog as a way to glean information out of the local repository
without running 'cvs' commands on the ,v files.

If you pass the -q switch to the RCS 5.7 commands, they will not whine
about unknown phrases. The warning message spews from the
rcs-5.7/src/rcslex.c::warnignore() function which is called from
rcs-5.7/src/rcslex.c::getphrases() when NextString is not one of the
known keywords.

A solution would be to ensure that the '-q' switch is being passed to
any rcs command that might run into a newphrase like 'commitid'

% rlog foo,v
rlog: foo,v: warning: Unknown phrases like `commitid ...;' are present.
% rcsdiff -r1.1 -r1.2 foo,v
rcsdiff: foo,v: warning: Unknown phrases like `newphrase ...;' are present.
RCS file: foo,v
retrieving revision 1.1
retrieving revision 1.2
diff -r1.1 -r1.2

One solution might be to modify lib/vclib/bincvs/__init__.py to
use commands like 'co', 'rlog' with different command-line args than

fp = self.rcs_popen('co', (rev_flag, full_name), 'rb')
fp = self.rcs_popen('rlog', args, 'rt', 0)

or the others that exist.

Another alternative might be to provide a patch to the RCS maintainer
to support any of the newphrase formats that CVS has introduced...
