@tm604 Do you think you might be able to give this PR a look?

I've been using this on a test environment, and I'm now happy with the way it looks. I think this can be merged and released to CPAN safely, since nothing will be using it.

After this is out, we can think about the order in which the API (jjatria/perl-opentelemetry#7) and the SDK (jjatria/perl-opentelemetry-sdk#6) PRs for logs support can be merged and released, perhaps increasing the required versions.

This sounds great, thanks - I'll try out the branch to see if any new or exciting issues appear, but on first glance it's looking good 👍

This was released to CPAN as 0.016001-TRIAL, but I expect it to be bumped to 0.017 in the next coming weeks.
