Describe the feature you'd like

Most of the exported functions of the type Span, in the tracer package, have a nil check in the receiver
That works very nicely when the the tracer has not started
So the end result is a noop

The function AddEvent is the only expcetion, can we consider adding an nil check to it?

Is your feature request related to a problem?

No response

Describe alternatives you've considered

For now I'm just doing the nil check in my own code before calling span.AddEvent

Merged. It'll be released in our next v2.1.0 release, which will be released as v1.74.1 for those still using the v1 API.
