Agreed. I think that the noise of changing all existing attributes to
have the marker would far outweigh the cleanliness of being
consistent. I was thinking of adding BKI_FORCENOTNULL which would be
specified on the attributes you want it. The FORCE in there representing
that the default choice is overwritten.

On a first glance that doesn't look too hard.
