Like netcdf, I'm not willing to maintain MPI support in netcdf4-python.

Ideally netcdf upstream support building both serial and parallel 
variants of the library, and having both installed.

Library users can then choose which is best for their use case.

This is something upstream needs to support. As long as we need to 
choose one or the other for the package in Debian, we will choose the 
serial variant as the lowest common denominator. This also has the bonus 
of not having to bother choosing an MPI implementation.

Kind Regards,
