this is not true. It solves a range of problems, e.g., in no particular 
order:


I'll be replying to one these at a time...

No, not true. E.g. 

schemes/riemann_surfaces/riemann_surface.py is neither "basic" nor 
dating back that much - it's also under relatively active development, see 
its header: 

- Alexandre Zotine, Nils Bruin (2017-06-10): initial version 
- Nils Bruin, Jeroen Sijsling (2018-01-05): algebraization, isomorphisms 
- Linden Disney-Hogg, Nils Bruin (2021-06-23): efficient integration 
- Linden Disney-Hogg, Nils Bruin (2022-09-07): Abel-Jacobi map 

It's using Voronoi diagrams from scipy.


Well, scipy.spatial.Voronoi was added in SciPy 0.12.0 
(https://docs.scipy.org/doc/scipy/reference/generated/scipy.spatial.Voronoi.html),
 
released pretty much exactly a decade ago -- 
https://pypi.org/project/scipy/#history

Next?
