From my experience the pins are only used for maintenance tests as required or for long term parking. Even towing between stands these days seems to be operator choice. Some insist, some just want the nose pin, some directly mandate that they're not used for towing at all to avoid any unpleastness. The risk of them being left in out ways the risk of a gear collapse during towing.
If you are only ever working with one operator then there is no real excuse for not knowing their procedure. If you are working multiple airlines and aircraft types then it is more likely that an incorrect procedure could be used.
