I ask this because of the recent news about Chrome browser vulnerabilities and I want to use my phone as long as possible. I have a 4a and it's the best pixel for me. It's got an earphone jack. It's not too big. It's easy on battery. It's fast enough for me. The newer phones don't appeal to me as much. So, I was kind of planning to keep using my phone after GrapheneOS no longer supports it. It made me curious about if the browser will continue to be updated after the OS is not.
Who knows the future. Maybe Pixel 8 might be something I like.
