I've no idea whether this is the case or not, but one thing you might
gain is independence from a third-party module. You could, for
instance, automatically AES-encrypt your data, but only if "from
Crypto.Cipher import AES" didn't raise ImportError. That effectively
makes encryption optional (the program won't barf for lack of pycrypto
installation), while still clearly being the default - and if you have
a nice loud warning, then it's clear that encryption is the normal
state, and the fallback is a lesser state.
