That would link the old and new version field - I thought of them as being independent. Basically, the old activity_version field would be a like a build number, increasing for every build, as we did before. It would be optional in Sugar 0.88. The "real" user-visible version number would be the dotted one in a different field.

An activity author who wants to support both could keep incrementing activity_version, and assign dotted version numbers independently.
