I don’t know, something about this smacks of “prestigious people reinvent obvious thing that was previously dismissed out of hand because it didn’t meet the criteria but if you’re prestigious enough people might bend the criteria for you”.
In particular I think the point was largely around having two dimensional projections. Using both sides is, in some sense, not really a 2D projection anymore since you have to interact with it by rotating it. And if you have to do that you’re most of the way to just using a globe instead.
The idea is that it lets you compact a globe from 3D space to 2D space with minimal distortions. You can carry a 100 such maps in less space than one globe would take. (Of course, if your requirements are to be able to see everything at once, then this doesn’t fit)
So what you said in the first paragraph doesn’t seem true to me, but if someone did invent that already and was dismissed i would be interested to hear.
