No doubt someone is going to try and defeat the interlock! Why? Someone will probably figure they can TRY and lower their electric bill if they have their generator running at the same time their panel is being supplied off mains power OR they don't want to have their lights go out for that split second when they transfer back from gennie supply to mains supply.
Trust me I know people that would want to do that.. All I say is " good luck" to them!
