The way I see it, the question is: how well can we maintain this distinction (column-backed fields in the model class itself, vs. non-field constructs in Meta). Right now the boundary between the two is more or less clear, with a few exceptions (ManyToManyField and GenericForeignKey, for instance). Once we grow support for CompositeFields, that will be another construct which looks kind of like a limited field from one angle, but actually resembles non-field constructs in a SQL table, too. If I ever manage to dust off and push through my ForeignKey refactor, even ForeignKey would become this kind of virtual construct -- just a named SQL constraint with some Python-level behavior tacked on top of it. To be honest, personally, I kind of like SQLAlchemy's approach, which simply puts all table-level constructs (columns, constraints, indexes) into model classes at the same level. It does not leave room for this kind of subjective bikeshedding.
