[SciPy-User] Alternative for scipy.sparse.sparsetools for use from outside of scipy

[Lev Konstantinovskiy]

What is the danger of using sparsetools from outside of scipy?

I found the Mar 2014 PR that made it internal but would be grateful to
know the reasoning. "MAINT: wrap sparsetools manually instead via
SWIG#3440" https://github.com/scipy/scipy/pull/3440

Thanks
