Is the istio-tracing deployment still relevant in Istio 1.10?

Is the istio-tracing deployment still part of modern releases of Istio or is it obsolete? If I have this deployment in a cluster running Istio 1.10 should I just delete it?

For background, I have a number of Kubernetes clusters that I manage which are all running the latest version of Istio. I just noticed today that in my older clusters, which have been getting upgraded through every Istio version since 1.0, there is an istio-tracing deployment in the istio-system namespace. But my newer clusters don’t have this deployment. Distributed tracing is working fine for both clusters.

Bump. Is there a better place to ask this question?
