The is a major problem for shelves (which I use often).

Some alternative needs to be put in place before bsddb gets ripped-out.

Was any of this discussed or thought through for PEP 3108?
What's wrong with deprecating in 3.0 and replacing in 3.1?
What advantage is there in ripping out bsddb during a release
candidate and crippling shelves on Windows?   
Why the rush to rip it out no matter what?
