But scipy does bundle a lot of external packages and then the license is
relevant.
I have no idea if this would apply here, but I find Sylvain's question
relevant if closer integration and usage within the scientific python, and
maybe Julia, community is desired.

LGPL is not as bad as GPL but still adds another hurdle, as far as I know
the scipy and related history.
