Just guessing....but everything that the engineers did had to be sold to management as having the potential for showroom floor sales....hence the streetable potential. It's easy to imagine them figuring that racers could easily change to a different intake.

I had an interesting conversation with the late Mac McKellar. He related that the factory engineers found much better cylinder-to-cylinder mixture uniformity with the dual plane intakes.

FWIW,
