Comment:
I think this is a bug, not a cleanup/optimization, and a release blocker
at that.
South had added defaults in the database until version 0.7.4; I think it
took another release or two to get rid of them completely. The realization
that defaults should never be left in the database (they should only be
used when adding new columns to existing tables, and then removed) was
christened in pain and angst -- some related to callable, as @timo noted;
another ill-effect, unique to Oracle, was that the presence of default
date-time values required special, non-trivial handling for schema backup
and restore (ask me if you want details; irrelevant here).
Defaults in a Django-managed database are evil. Kill them with fire.
(the change in type and severity is tentative, feel free to revert if you
have can convince yourself otherwise)
