From Cython or C one still has access.
I think this just refers to there not being any multidimensional consumers nor exporters in the standard library. So from the point of view of the standard library it is a bit useless; but it is not if one uses 3rd party libraries. The API itself is working fine, and you can e.g. export a multidimensional buffer and use it in Cython (defined __getbuffer__ for a cdef class and then access it through classname[dtype, ndim=...]), under both 2.6 and 3.0.
