I'm pretty sure I've seen cases where it does not, but haven't had the time to really dig into the code or repro, its just a note sitting in my long todo list.

Do you have a small reproduction that shows this bug?

Nope, I'm pretty sure that a metric needs a value before being present in the registry. PR is welcome :)
