When I last looked 9 months ago, there were libraries of the metrics side of the tree still marked as experimental, that you couldn’t successfully send metrics without using. And a huge memory leak in the JS implementation that was only fixed 15 months ago: https://github.com/open-telemetry/opentelemetry-js/issues/41...

Things, especially crosscutting concerns, you want to use in production should have stopped experiencing basic growing pains like this long before you touch them. It’s not baked yet. Come back in a year. Or two.
