Any plan to support this feature?

It's definitely still desired on our end, but we'll be adding support to receive metrics first.

As per discussion with @pront in #22529, I'm taking an initial attempt at implementing this. Considering the support of this functionality will enable both the OTEL sink and shipping metrics to platforms like Honeycomb.

Wondering about the status of this PR @britton-from-notion, is it still actively being worked on?

Hey friend, I've gotten quite busy but do genuinely need to do this PR. Just haven't been able to get to it.

I saw some similar PRs coming thru for OTEL sources that I was going to read through to kinda refactor how I'm doing this, but haven't checked back in. Definitely open to any help available to get OTEL metrics comin out of vector!!
