Hi @pkanal, do you have a timeline on this package? We're looking to incorporate the web-vitals library in otel as well and wanted to know whether we should pick it up in parallel, as we'll need it in the near future.

Also, for the CLS (and FID) metric, are we planning on keeping the default implementations for them? I know that they're dependent on user interactions, and so might never get sent until very late in the webpage's lifespan. Just wanted to know if there was any discussion on this edge case.

@shumone There's no specific timeline but I am actively working on this. The plan with the OTel Client Side SIG is to create a proof of concept in this sandbox repo and once we're happy with the API here, we will contribute this to the opentelemetry-js-contrib repo. If you're planning on working on this, we'd definitely be happy to collaborate!

At the moment we're planning on keeping the default implementation for CLS and FID. If you have any feedback for how to handle them differently feel free to comment on the PR for how they could be handled!
