A malicious admin can remove a non-malicious one and take full control of VTVLVesting.sol
It seems that your design for multiple-admins at AccessProtected.sol is very dangerous.
Any admin can add or remove another admin and take full ownership of VTVLVesting.
This is an unnecessary risk because probably you plan to have multiple users with multiple roles.
I recommend you to redesign your privileged users limiting them to only the action the will perform.
For example a users can create/revoke Claim for example.
Then a general admin is able to add remove those less privileged users.
