I'm also completely sick of fielding API migration emails from Google on mobile Android/Firebase. Feel like I get some "action required" every couple of weeks. This stuff saps our resources, both to fix it, and to diagnose if the issue even applies to us in the first place. If you are lucky Google includes details of the app using the API, but often this part is even left out.
Yeah the amount of disrespect of developer time they show here is crazy. You could have made the billing api backwards compatible for 10 years, its a super small api, but instead they force breaking changes every couple of years
Maybe it is a strategy for cleaning up old apps or something, but I doubt it
