That would be easy to do, and might be better given that right now the exact template names and such are implementation details.  

Although, now that I think of it, what name would you want to replace it with?  Most of the length comes from the `coord.SphericalCoordinatesBase` part - changing `_init_docstring_param_templ` to just `_init_docstr` or something doesn't really change it *that* much.
