I think one of the benefits of the current model was touched on earlier by
dstanek. If someone is working on something for their organization, they
typically bounce ideas of others they work with closely. This tends to be
people within the same organization. The groups developing the feature
might miss different perspectives on solving that particular problem.
Bringing in a fresh set of eyes from someone outside that organization can
be a huge benefit for the overall product.

I don't think that is the sole reason to keep the existing policy, but I do
think it's a positive side-effect.
