Guido states his opinion in no uncertain terms regarding pybsddb in
Python 3.0:

"+1. In my recollection maintaining bsddb has been nothing but trouble
right from the start when we were all sitting together at "Zope Corp
North" in a rented office in McLean... We can remove it from 3.0. We
can't really remove it from 2.6, but we can certainly start
end-of-lifing it in 2.6."
