I am agreed with you but still codeka point is valid. Granted for a given X there would be low values of L that make the contribution irrelevant. What I differ from you is saying that X is static. Einstein might helped to get the atomic bomb working faster, but there are good chances that eventually it would come out anyway.

Anyway, discarding contributions in that way seems disingenuous in the best case. What would happen if Newton wouldn't invent Calculus? Well somebody else would invent it later but we should be thankful that that didn't take 100 years more.
