I would serve if called upon, but I think it's best if we set this one
aside for E&J SoC (JESoC?) rather than GSoC this year.

Does someone feel comfortable asking James for his thoughts on this?

I'm not especially well qualified to mentor this, though I could assist as
a secondary mentor if needed. Any other Biopython devs/users well
acquainted with VCF/PyVCF?
