@mbrannstrom Do you want to weigh in on this?

The primary purpose of #2167 was to come to an agreement on the desired behavior (in 2021). Once we knew WHAT to build, then the HOW would be trivial. I could have provided an implementation back in 2021...

@joschi What is the reason to revive this issue now? Do we have a planned release of Metric 5.0 soon?

What is the reason to revive this issue now? Do we have a planned release of Metric 5.0 soon?

We have the following options:

• Release Dropwizard Metrics 5.0.0 without this. Then changing the format will be (strictly speaking) a breaking change.
• Release Dropwizard Metrics 5.0.0 with this change for peace of mind.
• Scrap Dropwizard Metrics 5.0.0 altogether because the demand has frankly been quite low. On the other hand most of the work has already been done.

I wanted to play with GitHub Copilot's agent mode and this issue seemed innocent enough, so here we are. 😅
