You're being downvoted but I mean this does work for some people. I definitely have coworkers who treat their work as purely transactional. Their goal isn't to be promoted or get frustrated at their job, it's to receive a paycheck and health insurance and get home to their families or hobbies. That's certainly a valid approach in any job scenario (not just SWE.)
I'm not quite at the level you've described, but I certainly have elements of it. I've been in the same role for ~10 years and have pretty much maxed out the expected raises/promotions of the role. It's not as satisfying as something brand new, but my pay to effort ratio is pretty ideal and I can work on side projects and learn new things on my own.
