Typically that wouldn't be a very good assumption, but the proposal isn't very controversial. We have multi-dimensional C style arrays, we have single dimensional std::array and we have variadic templates. Enhancing std:array to multi-dimensional using variadic templates to make it symmetric with C style arrays seems like an obvious thing to do in a TR, and doing it in boost is a good first step.

I looked at the documentation. It seems odd that you don't show an example of the syntax you are trying to achieve in user code. It is intuitive that array<int, 2, 3> my_array would result in something indexable with my_array[1][2]. The documentation should say so.

Can this library be made an extension of the existing boost array by detecting variadic template/C++-11 support at compile time? It seems it should be backward compatible with existing usage of boost array. I would prefer that to a new library.
