I suspect that developers do use those publicly available versions for testing,
but the 19x19 server allows
several things:
-- testing against a broader range of programs
-- publicly accountable results
-- game records
Tuning against just one or two programs can lead to brittle programs. Sluggo
reports that it did very well against GnuGo, for instance, but not nearly so
well against many other programs, due to the "evil twin effect" -- Sluggo knew
exactly what GnuGo would probably do in a given situation, so could find moves
which GnuGo was blind to.
It was effectively tuned to exploit weaknesses in GnuGo's engine, which can
lead to improper play which can be exploited by others.
