IMO, much of the "interesting" content may not actually be 3d objects,
but rather, information (text, models, images, sound, the works) which
you use the 3d objects to navigate trough and interact with.
Anyway, in my mental model, the answer to that is horizons. For a
document (akin to a wikipage), you may define an infinite horizon: all
revisions will be kept. For most 3d content, the default horizon, which
is to be defined -- a month, a week, 200 revisions? And for things like
position of avatars, zero: no revision control at all.
Alternatively, only record a revision when the object remains unchanged
for some period of time... but this is hairy to implement and I'm not
sure it would be worth it.
