In a few fields of rust we are starting to see a convergence of lower level libraries that then can be shared amongst the higher level crates. For example, wgpu is seeing broad use across a bunch of libraries from game engines to UI libraries. This then allows the shared libraries to be made more robust, with more shared resources going into them.

Does anyone know how much of this is happening in the matrix/array space in rust? There are several libraries that have overlapping goals: ndarray, nalgebra, etc. How much do they share in terms of underlying code? Do they share data structures, or is anything like that on the horizon?
