I would add that our project, imho, should be open and transparent. If we hide the internal workings from all but the cognoscenti, we are not achieving the greatest aim.
There are many ways to address DRV issues, without blocking all non-mainspace searches.
Internal searching while helpful, should not be yet another way to shield the world from the project. Quite the opposite imho. Forming a closed society is not going to be a productive way to show our supposed higher ethical standards.
