You can already change the Touch Bar settings in macOS to put back the default keys as would be on the physical keyboard; the problem is that it's still not a physical keyboard, and you get phantom key presses as you lay your hands around the keyboard to be able to push any key you want without even looking at the keyboard. Not to mention the loss of the haptic feedback.

The fact that Touch Bar is a "premium" feature, yet many folks would pay MORE to NOT have it, shows you that Apple merely doesn't want to admit the defeat, because there'd be plenty of people who'd pay more just to get the newer hardware without giving up the physical keys.

P.S. The same actually goes for the oversized Trackpad on the latest 2019 MacBook Pro 16" as well: I've enabled Tap to click on MBP16 as on all my prior MacBook laptops for years, and I'm getting phantom clicks everywhere all the time now; it's really annoying, and one of the reasons why 16GB Quad-Core 2020 MacBook Air 13" is on the only decent MacBook out there, even if you have an unlimited budget to spend -- I wish they'd at least offer more RAM on it, if that's their only actual professional machine at the end of the day!
