I think that most modern cyclist been a bit brainwashed by the trickle down from racing and don't really know better.
When I started I had 3x5 gears with a range of roughly 3x.
Top gear was from just over 100" down to roughly 35".
So I had to pick my own gears with care.
Now 2x10 with a range of 4.5x is standard.
In the same time the big chainring went from 53t to 50t and sprockets from 14t to 11t.
So top gear is roughly 20% higher but the greater range means that the lowest gears is also around 20% lower.
So there is lot less need to pick your own gears.
Once you start to look beyond "bog standard" gears then you start to realize how bad the "bog standard" gears are for average riders.
How many normal riders need to cycle downhill at +35 mph .........

But if you shrink all the "bog standard" gears by roughly 10%-20% to shift the gears to a more useful range then you'll probably fall into a marketing disaster because that implies that you're not good enough to use racing gears.
Hence the brainwashing from racing.
YMMV .........
