By far the main function of the tire tread is to evacuate water.

I think you'll find most of them are opposite. The fronts will V to the rear and the rears will V to the front. The rears drive the bike forward and the fronts get driven to stop.

I would tend to agree that running the V forward on the front could lend to hydroplaning. So you're right in that aspect. If you run a rear in the front in the direction indicated for a rear installation, you get the V facing forward. You want it facing back to channel water and for breaking grip. Hence running them in reverse rotation. I also think this is important for best breaking power on dirt.

My scorpion trails are opposite, front to rears. Sipes in a V facing back to the outside, but the rears have the V facing forward to the outside for best grip when accellerating.
