The poster said, "I don't think calculating the number of unique nodes at ply 9
is interesting because I think taking three-move repetition into account becomes
important after 8 ply."

There are already differences in the way people calculated shallower depths, due
to different interpretations of the en passant rule. At some point it gets
ridiculous, if you had to worry about 3-fold repetition, the 50 move rule, etc.
I agree with him that there are other interesting problems, like finding the
shallowest stalemate.
