Big agree on Golang. I had colleagues working with 5-6 JS microservices and they really wanted to keep span IDs so they can have sub-spans and unify semantic requests together (they also included background jobs processing) and they had to bring up a Redis container just to keep mappings of pieces of data every microservice has access to (e.g. order_id) and the actual span ID. It worked well in the end but it needed to be fully manually taken care of.
