Gearing adequacy really depends on where you live, what your commute is, and how fit you are. I used to have one "killer hill" on my commute that would often leave me dropping down into granny gear for the first year or tow -- then I got into better shape, and the middle ring was fine. I could probably ride my current (at least, before WFH) commute in the big ring.
It should be noted that I DON'T live on the north side of Seattle, or downtown San Francisco, or anyplace with hills like those.
So standard bike gearing is fine for my commute.
Weekends or vacations, when I want to ride up ridges or mountains? Darn those manufacturers, who don't give me a decent low gear on a road bike! or most touring bikes!
