As far as I understand WebRequest.PreAuthenticate is almost always good.

If I enable it even when there is no credential it won't try to authenticate, if there is a credential it'll. So is there any legitimate reason to set it False? Or is it OK to set it True even when there is no credentials?

And since it's quite useful why it's not enabled by default just like many other HTTP features?
