Many of those aren't features. I had a Note 9 and I have an S10. The in-display fingerprint sensor is more ideally placed in the S10. Literally just right in the display. It's the most natural position possible on a touch screen, if you're someone that uses your thumb to scroll/type like most.
I personally never used the iris scanner, so I won't comment on what kind of loss that is for those that use it.
What is the point of home button haptic feedback? Serious question. I had mine on the lowest setting possible. You can now double-tap anywhere on the screen to wake it. Much more useful and long overdue IMO. And you can even lift to wake, though I'm not fond of that setting and leave it off.
The lack of bezels make the holepunch display very much worth it to me. I'd never go back to bigger bezels.
Power button placement is something I get used to within a week. As a mobile tech enthusiast I switch phones often enough that I'm used to it being in different spots on different phones, but I understand I'm in the minority with this.
Only "features" the Note 10 is losing are microSD support and the headphone jack. The latter is quickly becoming a relic on every flagship, and the former is being compensated with much more base storage. Though, I understand why that's still a problem for some.
Security options, display, etc. are all upgrades and leaps forward IMO.
