The one thing I will say is... In education, geography specifically, they teach kids and test them on names of things like the Great Lakes in grade school.
Will new text books need to be ordered with this change? Will only some states do this? Will educators accept 2 different answers? What about state testing? Will some kids be taught names can change with every administration and they will react saying what's the point in learning names of places if they always change? Become apathetic? Will classrooms argue over the names of geographic bodies based on politics?
This kind of trolling, while stupid and idiotic, do impact and cascade down to other places we may not think of right away.
