As mentioned in the post, the eventual home for this functionality will be in OpenTelemetry. Specifically, it will eventually be integrated into OpenTelemetry JS (https://github.com/open-telemetry/opentelemetry-js https://github.com/open-telemetry/opentelemetry-js), which is being built up from the start to have the core parts be usable in the browser. Disclaimer: I work for Google and was the original author of OpenCensus Web, and coached Cristian, the intern who wrote the post.
