Between the breast size mod and the jiggle mod, I'd say it's more about
disrupting balance.
Well the size mod can threaten said balance...
... however:
The jiggle mod answers a long standing complaint this humble artist has had against digital FX in movies and character modeling in games overall...
Best example, the fight scene that killed the Matrix trilogy, a river of digital porcelain dolls cannat make up for the fact that it looks fake.
We people of the Trekkie oreintation know that humans are "bags of mostly water". Look at still frames of boxers in the ring, if it isn't bone, it sloshes like a water balloon. Just like micro-expressions in a coversation, they are present only for fractions of a second, but we register them whether we are aware of it or not.
No matter how highly detailed the model is, if it doesn't slosh around like real people, it will never look like real people. It's jusr another virtual poerelain doll.
As far as this artist is concerned, that (and a couple other complaints) renders the majority of 3-D animation, artistically inert.
As far as balance goes, this community could only exist in a culture that is thoroughly blighted by coerced conformity to censorship.
