Well as an iOS user, the last iOS release fucked me up pretty badly. Ergo, I would assume the same is possible from Google.
What I'd like is an exit route for my hardware aka LineageOS. But of course the core of Android is Google Play Services, not the OS so that's a painful situation if you want to retain some apps when you switch over.
I used a Pixel 6A for 3 months while I was travelling internationally and I liked most of it.
