I fully agree with this and there is a major error in reasoning regarding SIM cards. In real life, a phone gets much more often swapped than a SIM card. A SIM card is mostly a long-term item and it is a nightmare to have PIN, PUK etc added manually again after replacing a phone. Additionally the "mask" option needs to be turned off and and admin should be able to run a report about all existing SIM cards. The plugin was really great tool for all that.
