It is still a vote to change and a vote on dogma. Sooner or later, they will push a vote to go the way of the PCUSA. That is the problem
You cannot imagine changing minor points of doctrine. Considering we Protestants have nothing like the Pope and do not consider tradition infallible, you are trying to hold us to your Papist standard. We can change minor points of doctrine and practice, so long as they do not conflict with Constitutional standards, such as the Scriptures (the sole infallible rule of faith), followed by the ecumenical creeds (since they faithfully summarize the teaching of Scripture), followed by the Westminster Standards (insofar as they summarize the teaching of Scripture).
