If you can't get 12 people to test your app, how do you expect to get actual users? I believe this is a good change by Google to prevent slop on the store
Look, not everyone is chasing subscriptions, ads and thousands of users, and with Google constantly squeezing side-loading, the Play store is becoming the only distribution channel left on mainline Android.
But yeah, I guess it's not a big loss, most people install 0 apps per month anyway.
Just like Google did with its Clock and Messages apps. They have billions of people to test their app. If it compiles, ship it.
