You're implying some difference here that I don't see.
Both platforms need some way for the client to register to their respective push services, Apple needs an Apple account, Android needs google-services.json.
Both platforms require your app to generate a token which the platform's respective push service holds, and send it to your server which you then use to identify the client you're pushing to.
Apple also requires the Auth p8, Bundle ID, Team ID and Key ID, which are roughly equivalent to the contents of the google-services.json.
On iOS you don't need a separate binary, the server-side infrastructure is not scoped to individual apps.
I don't think that it's possible on Android.
