 Description   

In 2.6 the new aggregation with $out collection specified will drop the $out collection if it already exists. There is a discussion about making a change in that behavior, but until it's sorted out we need to warn users so they don't choose their main collection as $out.

Will close for now. But please feel free to reopen if you want us to perhaps emphasize more.
