FWIW, I personally doubt that we would make the filesystem choice for  
the vast bulk of ZC's past and future engagements.  I would also be  
surprised if we did not continue to use the ZODB as our primary  
persistence tool (among others, already including the file system and  
RDBMSs) in the future.

We run regular automated tests.  We ideally make sure that the  
changes are ones we agree with or ones we can opt out of.
