does this actually work? there's no guarantee that there is an active span during shutdown (I feel it's likely that there is not one), and also if there was an active span there's no guarantee that it's the root span. We do have an API method that would help, LocalRootSpan::current() however I think you need to re-think when this runs.
Perhaps a completely different approach where it emits metrics rather than attaching metric-like values to a span? You could do it with async/observable instruments.

@brettmc , yeah I think you are right. we can take this up as a completely different way it emits metrics than span attributes.
I'll rework on this PR.
Thanks for the suggestion.

I think this line excludes all versions. Since you're not actually hooking methods, you can just remove this line since it should work against 8.1
