From what I can tell, this is all opensource using their publicly documented API. That is, you could implement the same support for GCP in your own auth backend product, and you could implement the same support for your own cloud platform in Vault. So… I don't really get what you're talking about in this context.

"We're working to enhance the integration between HashiCorp Vault and GCP, including Vault authentication backends for IAM and signed VM metadata."

There's not much detail in that. But, you could certainly read it in a way that using Hashicorp products might be lower friction than using other products on GCP.
