OTOH, designing an API without reference to any implementation can
produce a hideous mess full of WIBNIs.  One cure for the problem, if
you have the resources, is to produce two implementations at the same
time.  This trick was used when developing the IBM 360 architecture,
which was designed to be executable on a whole variety of systems with
different price-performance.  The IETF's requirement for two independent
interoperating implementations of any protocol to be standardized is
probably related.
