When a user visits a play.google.com URL Google wants to be able to show either an "install" or a "launch" button contingent on whether the app is already installed. In other words, blame Google product management.

this doesn’t make sense and sounds like an excuse IMO. Instead of the browser enumerating all apps, why can’t it check when you visit a page if the current page (ONLY the current page) is installed as an app?

  How would the OS know if the app that the browser is querying about is actually the current page? For all the OS knows, the user might be quickly visiting a ton of play.google.com pages for the top 1000 apps on the app store.

      But God forbid users learn how to use their device. All of this could be prevented by having the users manually pick the application instead.

    > How would the OS know if the app that the browser is querying about is actually the current page? Maybe i’m missing something, but it sounds like it would be easy for google to support this functionality by letting developers configure this in their app “bundle”. A property that tells the OS “my app is related to domain example.com”. Make it an array of domains if you must.

      Intent filters can be for domains. It's how deeplinks work. But with querying being locked down you can't know what apps can handle a deeplink.

Elaborating on the sibling's comment: There is already such a property that apps must set in their manifests in order for them to be able to react to links/intents for domain-associated-with-the-app.com. But it doesn't address the question of how a browser is supposed to be able to open links to domain-associated-with-the-app.com in that app, without Android revealing to the browser whether the app is installed or not. In short: The browser will, by construction, be able to determine which apps you've got installed or not.

        I mean, do Windows or macOS tell the browser which mail apps you have installed when it handles a mail:// URI?

        No, but web browsers do have the ability to ask the OS which application is associated with a certain url type. But it doesn’t leak that information to web pages.

A minor UX difference doesn't really feel like a great case for reducing user privacy, it makes me a little concerned about priorities... which I already was, really.

I don't buy this. Google has this information on their backend, they don't need to query any local state. Indeed, when I visit a play.google.com URL, google checks if my browser is logged in or not. If it is not, the default is "Install" no matter what. If I do have a session, then it's either "Install" if I don't have it installed, or "Install on more devices" if I do have it installed.

  This is true, but if they didn't allow this permission for other browser apps that would be anti-competitive.
