Who do you work for - in over 20 years in the industry I have never known any major airline insist on fitting ground lock pins for pushback.
In fact the ground-pins are kept on the aircraft and there has been a continued effort to stop people using 'spare' ground pins that cannot be controlled as they tend to get left in - turnbacks due to pins left in and gear retraction failure are not unkown.
