As a counterpoint, I don’t want to download apps when webapps suffice. I appreciate when a right click gives me the options I’m hoping for rather than a set of generic Chrome actions that aren’t what I want. I also appreciate when copying works how I want it to (e.g. copy paste in google docs or Figma work as I expect it to, including all styles). And hijacking browser history doesn’t seem to me like it adds much exposure, because the attack vector is still there without browser support (when a user enters your site, auto redirect to google.mydomain.com, which then auto redirects to your content. Back button now will return you to google.mydomain.com without relying on custom browser back button shenanigans)
