The cases you mention are exactly why it is best to not attempt to apply the logic throughout the code automatically but to write it manually where it makes sense to do so. Except in the case of live tracing, where you can use matchspecs to setup traces on functions you care about.
I'd also suggest checking out existing instrumentation libraries for Erlang, so maybe you don't need to write your own:
- https://github.com/open-telemetry/opentelemetry-erlang-api/ implementation of the https://opentelemetry.io/ spec.
As well as the Foundation's Observability working group, https://github.com/erlef/eef-observability-wg/
