Some platforms do this. My understanding is that they're especially motivated by the fact that many people don't really distinguish between mybank.com/changepassword and mybank.attacker.com/changepassword. However, it really infuriates some vocal technical folks (e.g. https://www.androidpolice.com/2020/08/13/google-resumes-its-senseless-attack-on-the-url-bar-hides-full-addresses-on-chrome-canary/ https://www.androidpolice.com/2020/08/13/google-resumes-its-...). I think the compromise is good: hide the full URL by default, but have a setting or some affordance to show the full thing to people who do enjoy looking at it.
