@spica29 the PR looks reasonable but I'm wondering what's the use case for this. I've never seen any other value besides "servicenetworking.googleapis.com".

Hi, we are trying to set up a PSA for NetApp and it uses another service: "netapp.servicenetworking.goog". Here is the documentation. I believe that we often just see GCP as a service producer, but we can also have third parties. There is not a lot of documentation about it though.
