I've gone iPhone -> 3GS -> 4 -> 5s -> 6s -> 7 -> SE 2020 -> SE 2022.
The Mini never interested me. I love the SE. I love the home button and TouchID. I love the traditional size. If I want more I have an iPad Pro (12.9" original 2015 model bought in 2015 -- the battery still lasts 2 weeks with my usage pattern) or M1 Mac Mini with a 32" 4k screen.
If they don't make a new SE model I don't know what I'll do. I guess, firstly, get a new battery for it before it's out of the support window. Maybe sometime next year. And then see how long app updates support whatever the last OS version it will run is.
The ONLY thing I'd change in my SE, if it was possible, is more than 4 GB of RAM. The latest models have 8 GB and the others at the time the SE was sold already had 6 GB.
With recent system updates I'm getting a lot more of applications restarting when I switch back to them. This is mostly not a huge problem, except that the X app loses your place in the "Following" stream if you're more than a few hours behind and the app reloads.
