Yes it is.
The windage tray helps to de-aerate the
oil in the pan so the pickup has less of a chance to draw a foamy slug of
oil up and push it out to your rods and mains.
When the engine is running you have about one to one and a half quarts of
oil "wetting" the various internal parts of the engine. You could have another quart waiting in various places to return to the pan and don't forget the hurricane of oil being whipped up in the space of the crankcase as the rods discharge their oil from the side clearance you provided when you built the engine.
This stuff eventually comes to rest in the oil pan as an aerated oil foam. The windage tray helps protect it from getting whipped up one more time by the crank and rods. This relatively peaceful stay in the oil pan gives the air bubbles time to dissipate before the pump sends the oil out to work again.
