Sorry, this comment was mainly just providing the previous user with a correction because they seemed to think that the other person that they were replying to was talking about forcing people to use phone apps, which I assume we all agree is bad and would likely work if there were a concentrated push for it.

Concerning your points after “using the browser”: I want websites to use replaceState and manage their own intra-page navigation with a cookie. They can still intercept the back button as they do now, but they should only get the single history entry until they switch to a new page, if they ever do.
