"I take issue with the current standards."
"No, the current standards are good because they're the current standards!"
Even if I could see how your objection addresses the point, I would emphasize that, while the three crankset configurations you mentioned are the most common available on modern road bikes, they are hardly the only available. For example, Shimano's current lineup of high-end road chainrings does include a combination with a 12-tooth jump (54-42 for Dura-Ace FC-R9100) and one with a 10-tooth jump (46-36 for Ultegra FC-R8000).
As far as shift quality goes, it's certainly true that a well-adjusted FD paired to a well-designed 50-34 can make the shift consistently. But the shift is still large in ratio, requiring more compensatory shifts in back. And, for the upshift, it fundamentally takes longer for the shift to resolve because of how much rotation has to happen between the initial shift engagement and when the chain has been fully lifted into place. It's not illogical for someone to prefer smaller front jumps.
It is, however, illogical for someone to bloviate at length about things like this while purposefully trying to misrepresent someone's point. Lol @ going into logical fallacies 😂😂😂. Want to go back to Eddys era climbing cassettes too?
If you want the range, there's a drawback that requires shifting maybe 2 cogs in the back to end up where you wanted to be. Can be done with one motion.
How much longer are we talking about for this inconvenience? If you want to talk about progress, it's a non issue with electric shifting. You can still pick the rings you want these days as well. Gravel cranks come stock with closer ratios but you give up the range. Triples have their own set of problems or nuances so to speak.
The ten tooth ultegra crank is usually installed in cross /gravel setups more so prior to grx. You can do just about anything if you're willing to live with the shortcomings. This idea of the shifting being so inconvenient is laughable though. It's a technique and tuning issue. 'stressing the gears' isn't really a thing anymore.
