While this definitely makes sense, I wonder if we could make the doc more helpful with a link to https://opentelemetry.io/docs/instrumentation/go/exporting_data/#sampling?

open-telemetry/opentelemetry-go#3585 changed the location of the sampling documentation.

It changed from https://opentelemetry.io/docs/instrumentation/go/exporting_data/#sampling -> https://opentelemetry.io/docs/instrumentation/go/sampling/. I'll update the link in the comments - 18970fd.
