Gibson has a history of hyperbole in it's marketing that pre-dates all of our lives. guaranteed. They have innovated and tried new things at all periods of thier career, going back to the 1890's. some things worked, many did not. stuff like the eye guitar or the reverse flying V are just part of a long established pattern of innovation/pandering.
Probably very difficult to reach a consensus of opinion in those days without the incredible communications tools available today, not to mention the fact that there were far fewer of us in those days, the combination of these & other pertinent era related facts making it much less likely for guitarists to have gained or passed on substantiated useful knowledge about new technology effects on traditional instruments.
