Except for one thing: forums other than OMNI generally enforce the prohibition against content-free post padding. So I doubt this particular consequence will materialize.
I really don't understand why some people are so worked up over this minor feature. But then again, I virtually never visit OMNI and I don't measure a member's value by his post count. Post count isn't part of your anatomy, so there's really no need to enlarge it.
I am guilty of it in some of the 'Lounges' that have been established. There are jokes, short little rambles that have nothing to add to them, etc that go around. In a way the 'Lounges' are pre-OMNI places for those without OMNI privileges. Don't get me wrong, there are some great posts and first posters that post to the 'Lounges' that add to the content, but it is just a game in there.
