That's beyond the current scope of Scipy, so we'd have to seriously think
about it. Is the API built on or similar to scipy.sparse? Do you have your
code already somewhere public, so we can have a look at it.

Anything in the Python stdlib is OK to use in Scipy from the point of view
of dependencies. So it depends on performance and other technical aspects
like maintainability/scalability only.

The testing guidelines are at
