From the docs: http://www.postgresql.org/docs/9.4/static/cube.html
"To make it harder for people to break things, there is a limit of 100 on
the number of dimensions of cubes. This is set in cubedata.h if you need
something bigger."
Thus the limit is indeed arbitrary - though if you decide to recompile to
increase that limit your expectations should be sufficient tempered since
likely few (if any) people are using cubes with 100 times the default limit
number of dimensions.
Given that R-tree is 2-dimensional I'm not sure how it is relevant. The
docs also indicate that GIST effectively supersedes R-Tree as an index
method...
