## What changed? In most cases, use `metadata.ValueFromIncomingContext` instead of `metadata.FromIncomingContext` to get grpc metadata. (History client `StreamWorkflowReplicationMessages` still uses `FromIncomingContext` because it copies all headers.) ## Why? `ValueFromIncomingContext` does less allocation when you just need to access a specific header. ## How did you test it? existing tests
