Chrome has sign in with Google and Google Passwords, Edge has Microsoft Sync. Both features intended to bring users into respective walled gardens. If Edge gets more popular, they will try to Embrace Extend Extinguish the web platform, but currently that won't work as they don't have enough users, so their devs are working on engine adjacent things like the Developer Tools panel.

Literally every browser anybody cares about has a passwords/setting sync function. Chrome, Edge, Firefox, Safari, Brave, Vivaldi. I don't think spinning a basic feature as a dirty ploy is terribly useful, or honest.
