Revocations are for apps being malware and nothing else, much like macOS Gatekeeper (Apple doesn't even revoke certs used by Warez groups to sign cracked apps).

Automated bans can be an issue, but that's an edge case. Google already had the functionality to 'revoke' an app if ordered to do so by a legal authority.

It is much more important to make a real world attack - something that is draining wallets of ordinary people across Thailand/Brazil/SEA in general - harder to achieve. One thing is a political goal of some people in the west, the other is an ordinary person not having the money to feed themselves because a scammer stole it all.
