Lint needs to have a feature enabled that's transitively enabled if the full workspace is checked, will do that later.
The external types check is broken because the nightly used is too old and axum unconditionally enables the diagnostic attribute on nightly without the feature flag because they assume everyone is at least on a nightly that is 1.68

I have a few minor points. Feel free to ignore it if you don't care about the features as this should never break anyone unless a downstream crate or cargo make breaking changes and at that point all bets are off.

I think this could also be merged without waiting on tonic by adding a dependency on http@0.2 to opentelemetry-otlp and using that for tonic-specific errors since that's the only place where these types figure as far as I could find.

Sidenote: The some tests in this repository seem flakey? Locally I sometimes have to rerun the tests a few times before they pass. Weird.

Yeah feel free to report those test in #1559. Most of them are because global setup / env vars and we are working on addressing them as they pop up

(missed that one during the last rebase)

[NOBLES5E]

I was wondering if this is planned to be merged anytime soon?

I'm intending to get this over the finish line eventually, issue is just that the tonic PR is still pending
