While I will agree that it takes a long time to reach everywhere with new features in Maps, I'd say the recent macOS Monterey update was a major improvement in performance/reliability, so the article doesn't really resonate for me.
I IMMEDIATELY noticed the improvement in application startup times after upgrading and have seen a big difference between my work laptop (macOS Catalina) and my personal laptop (macOS Monterey). Everything has been more stable in Monterey for me personally. I've noticed that the weird occasionally-crash-my-laptop-when-using-a-dock bug has been resolved. Connecting my AirPods has become more reliable and the connection doesn't flake out anymore.
