Perhaps the class-level default would be the old one, but the
constructor-argument-default the new? E.g.:
class BlobStorage:
strategy = 'naive'
def __init__(self, strategy='scalable'):
self.strategy = strategy
Hmm, but OTOH, this is not likely a case where we have to worry about
old persistent data ;). I guess old config files need to continue
to work as expected, which means that the directory itself needs some
kind of metadata file which indicates the strategy: in that case,
the absence of the file would indicate the need for the BBB version.
