Its not so much about ensuring the best tool chain is used, but rather about setting the lowest bound of quality. By being slow moving it avoids the potential for temporary regressions. It is also ass-covering by demonstrating you followed "industry standard procedure". If you do something different, even if it is quantifiably better, it might make for a stressful deposition explaining why the worse but standard approach wasn't used instead.
