Apparently you are not familiar w/ the technical history of cycling as a sport.
Cramming as many cogs in between the low & high range for efficiency has been driving (sorry) force in drivetrain development for over a century.
3 to 4, 4 to 5, 5 to 6, 6 to 7, 8 to 9 , 9 to 10, 11 to ? All for the same reason, Range & smaller steps.
And that's how it was/is and will be.
For the 126mm C&V folk (myself included) 7speed worked a treat, with greater efficiency than 6.
