I think you can omit type.hpp.

The answer is probably yes for lapack, judging based on the existing code base. I also see sparse_traits.hpp, which doesn't get included in this way, but is not needed for lapack.

I guess it's OK that type_traits.hpp includes type.h and type.hpp. So the question revolves around traits.hpp. All traits.hpp does is to include vector_traits.hpp and matrix_traits.hpp, and you are wondering whether it should also include type_traits.hpp. Its name suggests to me that it could include it, but I don't know whether it is supposed to include it.
I think it would be reasonable to change traits.hpp to also include type_traits.hpp, and change all code that includes traits.hpp but don't want to include type_traits.hpp to directly include vector_traits.hpp and matrix_traits.hpp.
