Adding on to that, “QA time is expensive” too. I’ve learned from experience that trying to tweak well established repos/libraries rarely gets management’s approval because the extra time it would take to QA and regression test is considered pure loss. Better to leave it be and force the new code to work with the old stuff. That way it is at least billable.
