We're planning on adding support for opentelemetry v1.22.0 in our upcoming v3.x.y release, which should be available in 2025Q4.

BTW, google-cloud-cpp[storage-grpc] is currently broken in vcpkg because of this.

To be honest, I recommend google-cloud-cpp team merge code that can successfully build into main branch and release branch.

I am source code / docs contributor for Microsoft, Amazon, Google and others.

This style of issue，I first met. please accept my recommendation!!!
