I would strengthen this to just short of actually requiring tests.  They
don't have to fit a specific test runner:  a Scheme script that prints
messages when tests fail will suffice.  This is 2015, and unit tests
should be a standard part of practice.  Exceptions would be when the
sample implementation is trivial and/or not really meant to be used,
just a proof of concept.  (My upcoming SRFI on ephemerons will have
a completely portable implementation except it won't actually work
with any GC.)

It is revolting to have no better reason for a rule of law than that so it was
laid down in the time of Henry IV. It is still more revolting if the grounds
upon which it was laid down have vanished long since, and the rule simply
persists from blind imitation of the past. --Oliver Wendell Holmes Jr.
