while managing multisig contract , guardian can add different multisig addresses to the storage , that's while there is a maximum number of how much MULTISIG addresses a contract may contain . it is also possible to disable or enable a specefic multisig . that's while its not possible to unregister a multisig , if a guardian was planning to register 10 mutlisg to the contract and he ended up adding a wrong address accidently , then there is no way that the guardian be able to add those 10 to the contract . he can only add 9 more .
recommendation : consider adding a function to unregister an address
