I’ve always thought of this notation as describing the stacking of cubies
(not to be confused with stickers), where in the normal Rubik’s Cube there
are 3x3x3 = 3^3 = 27 cubies.

In MagicCube4D, there are 3x3x3x3 = 3^4 = 81 hypercubies. Of course we
only see the stickers in the program.

So the notation is not obsolete in higher dimensions and naturally
describes the structure. It still makes sense if the notation refers to
size like you described for the 3x3x3 too. From a vertex, you can move 3
units in any of 4 directions (x,y,z,w) to reach another vertex.
