Yay, another "lets enforce our products to end users" on the cover of "security".
Can't wait for Google to remove the checkbox on every Android for "allow 3rd party software install", cause you know, it has to come from Google Play else it's OMG dangerous, and all the users are dumb and check the checkbox and install random apks. And look there's a nice illusion of choice, you need a procedure so complex that almost no one will be willing to do it (and thus you're forced into Google Play).
What? This is the same as the Android feature. External installs are blocked by default and the user can change that setting and acknowledge the security risk.
