Any benefit to cutting holes in hood underneath scoop?

I would not cut a hole in the scoop but put water drain hole(s) in the air cleaner pan with tubes to run rubber lines for water drainage, if I was to be caught in the rain.

Think AAR / 6 pack set ups. They do this.

Somewhere I had seen a double open ended scoop. The best I can see from this is directing air to the air cleaner more directly than just an air cleaner sticking through the hood.
