> But even if that was the case, is there any value for a receiver to be receiving those?

Yes, radio propagation is an entire academic field to be studied :)

In addition, if you have enough receivers you can use that to run something called MLAT [1] to also pick up GA aircraft that just have a transponder but no GPS. The more the merrier.
