Just to make sure, does this excluding of mlx5 happens immediately, that is, applies also to all non committed patches that you already posted? IMHO - I think it should be the other way around, you should get approval from sub-system maintainers to put their code in charge into auto-selection, unless there's kernel summit decision that says otherwise, is this documented anywhere?
