The Unknown Limits
When I heard of the renaming, my immediate thought was "Meta Incognita" - the name given to part of Baffin Island by Martin Frobisher in 1577! (https://en.wikipedia.org/wiki/Meta_Incognita_Peninsula).
It isn't, perhaps, an obvious link to one not conversant with the Polar Regions, but I think it does indicate the direction that the new entity is likely to take! "Limits? What Limits?"
