In the first iteration, we will be extracting metrics from traces, and they will already have enriched attributes as labels. We will enhance this later, for now, they are just pass through. If requires, we can check if the metrics contain API and service id, and if not, we can drop them.

Yes, this will be handle by default for deserialization exception handler - LogAndContinueExceptionHandler. So it will just be logged and such messages will be dropped.
