has anyone thought about / implemented any level of trace / extension support for Adobe ColdFusion and / or Lucee in the opentelemetry java instrumentation https://github.com/open-telemetry/opentelemetry-java-instrumentation/ ?

Fusion Reactor now has open telemetry. I'm currently trying to set it up with nodejs, which isn't 100% simple. I think the Java libs will be much easier https://docs.fusion-reactor.com/Cloud/OpenTelemetry/OTel-shipping/
