"the download of these apps will be completed through Google Play" (https://support.google.com/googleplay/android-developer/answ...)

So you'll still need to have that installed, and probably to have a Google account?

And Play Integrity and pairip will stay there and won't matter, if so...

Not to mention the annual 5000$ and limitation to the US.

This seems to be a pointless swindle, by and large.
