I've had a Google developer console/play account for a decade+. Recently had to send some proof of identity stuff in their anti-spam thing -- which I did because who knows one day I might care about the account -- but I haven't released anything there in eight years. No threats of closing my account.
Did they instead just warn that they would unpublish the app? Google does have minimum API levels that they slowly move forward, and they will unpublish your app if you don't periodically rebuild and resubmit.
No, I got the same message. It was very clear that I had 60 days to publish a new app or an update or my entire developer account would be closed and I would have to apply and pay all over again.
Ah, interesting. I guess it's that I did have a popular app on there (which was then removed after I completed a technology sale) and my details are verified.
They will suspend the account if you don't complete identity verification, though supposedly you can reinstate it if you disclose your personally identifiable information.
