You should be fine on gOS for 6 yrs+, which is how long google promised to keep up with security updates. The device tree (think hardware drivers), which is what google removed with pixel 10 is what is causing grief, is already there for lower pixels. Unless, of course, google comes up with some new fuckery to invalidate the usability of the security updates (pray I don’t alter the deal further…)
Today’s equivalent is building your own ebike, and it’s awesome and way easier than rebuilding an engine.
