It matters because of the differences in design between the spar and belly skins on the -6 and -7. Thinner belly skin and beefier spar on the -6.
So did you or did you not witness an RV-6 wing being load tested to design limits with the belly skin and screws in place?

The wings on all the models flex under +G load.
The top skins get slack and the bottom skins get very tight (as expected).
With all of the screws in place, some of the load being carried in the bottom wing skins is transfered to the fuselage belly skins (regardless what model).

All of this is true. But it doesn't answer the question of whether the screws are structurally necessary for the RV-6 wing to reach it's design limits.

Economics. Do you have any idea what it costs to develop an aircraft design from scratch? It's much easier to reverse-engineer something that's already flying. Say, like a Stits Playboy. :)
