> They are optional while the previous major is still maintained.
I don't think there is such a choice on Pixel phones but I'd be happy to be proven wrong. When the next major update is available the phone just asks to update to it every few days (but won't do it without user consent). I don't think there's security updates on a given phone for old major versions when a new one is available (there likely are for older phones that don't get the major update however).
Thank you for your explanations on flash wear, makes sense. Taking a low value of 13TB endurance (64GB times 200), this is still 7GB per day for five years and I don't think app updates can consume that much.
