As dappName needs to be set in MemberRoles, users can mistakenly set it to something incorrect and replace their current member role contract with it. It will cause them to lose the control over their organisation. This is unlikely to happen but we can add a check in Master.sol to make sure that only MemberRoles with correct dApp name are added in new versions. This can be done by creating an instance of the member role contract using the Governed Interface and then checking the dApp name.
