If Google isn't able to shut it down or providing the infrastructure necessary to keep it running in some way, why pay them at all? Whatever path towards work that you say could happen to support it in the future could just happen now instead. If that's too expensive for the customer or the local partner to consider, I have to question what this setup is even helping hedge against at all, because the whole point of it seems like it should be for the customer to be able to put in whatever work they need to up front to be able to avoid being forced to deal with it on a timetable they don't have control about in the future.
It sounded like Google was providing all the software necessary to use a cloud system effectively, including IAM. And you could get all of the other GCP services like BigQuery or PubSub etc. I don't remember what it was called though.
So that seems to be the value add. Of course the software will eventually need updates...
