Comment (by yuvadm):

 Replying to [comment:3 charettes]:
 > I might not want the existing rows of the altered table to be equals to
 `''` but a totally different value (e.g. `'active'`) even if it's not an
 explicit `default` value used by the application.

 like South did.

 This happens even for new fields being added. I would argue that any
 existing field change is a data migration anyway, and requires manual
 intervention.

 In any case, my complaint pertains to new fields being introduced, and in
 which case `default=''` is alread assumed by Django in any other aspect.
 So why not in this aspect as well?
