Did you read the part where it took multiple months to continue because of slow replies and non-working tooling from Google's side?
It's also pretty expensive for a relatively niche app, it might be fine if you are Dropbox or a big VC funded Mail app but for smaller companies it's not "easy".

How would Google find out if the version that they are "scanning" is the same one that gets uploaded to the app store on every small app update? Zero, so there's no security benefit.
