This reminds a lot of the hype around traffic signs and the font "Clearview" being better for driving. The data collected was the legibility of old signs vs new signs but never accounted for the control of replacing the worn/faded signs with new signs using the old font, or other types of signs.
Turns out it was simply replacement of old signs, and that Clearview actually had reduced legibility in negative-contrast (black on white, instead of white on green).
I'd bet that research would show something that the benefits of this come with cons.
