So... this requires cooperation from the underlying libraries (numpy, pandas...) - what is the likelihood of said libraries adopting this upstream vs Weld having to maintain their own shadow implementations for the foreseeable future?

Numpy et al of course already have N python acceleration frameworks hammering at their doorsteps to integrate more closely...

How much cooperation is needed though? It seems to me that all that numpy pandas etc. need to do is maintain a stable API, which they already do AFAIK.
