Except this is not going to be an independent Ukrainian church. It is going to be an exarchate of the Ecumenical Patriarchate. They will have no authority to appoint their own bishops, canonize saints, or make any decisions regarding their relationship with any other Orthodox Church. All such decisions and authority will reside in Constantinople.
Not that it makes much difference since not a single canonical Orthodox Church outside of the EP recognizes this farce.
Much like now except goodbye to the Russian Orthodox Church.
