No, because I think that it has nothing to do with cubing
Refer to what
@Kit Clement said. It's really just subjective, according to Wikipedia "
Speedcubing (also known as
speedsolving, or just
cubing) is a sport involving solving a variety of
combination puzzles, the most famous being the 3x3x3 puzzle or
Rubik's Cube, as quickly as possible."
We are trying to solve a "combination puzzle". Well what is a combination puzzle?
If doing a fractional amount of research we find that "A
combination puzzle, also known as a
sequential move puzzle, is a
puzzle which consists of a
set of pieces which can be manipulated into different combinations by a
group of
operations. Many such puzzles are of a
polyhedral shape, and consist of multiple layers of pieces along each many axes which can rotate independently of each other. "
Notice it say "many", it does not say all. looking at examples we find many we associate with "cubing", Pyraminx, 2x2, 3x3, Megaminx, etc. We also find puzzles that do not belong in the WCA like Pyraminx Crystal, Void cube, and so forth. Upon further inspection of the page you come across "2-dimensional" puzzles. While these do not consist of multiple layers we already know that combination puzzles are not restricted to that. Under 2-D puzzles we see the Fifteen puzzle.
Looping back we have Fifteen puzzle = Combination puzzle = What cubing is about solving.
When we cubers think of "cubing" we will associate with what we're used to or, the "norm". But it does still include less conventional puzzles.
Now, I am in no way saying it should be added I am totally against it as you can see in other posts. But what I
am saying is that saying, "No, because I think that it has nothing to do with cubing." Is very naïve and totally false, just because you feel a way does not make it so. If that were true Clock would probably be removed as an event because many "feel" it doesn't belong.
