Hi Michael. This deprecation notice appears to be about GitLab's metrics
feature, which they describe as a managed Prometheus instance and
integrated dashboard solution for their enterprise product. Apparently,
they're replacing that with a full observability offering. In case
you're curious, they also say [1]:

  This deprecation does not include:

  - Deprecating alerts for Prometheus
  - Capabilities that GitLab comes with that allow operators of GitLab
    to retrieve metrics from those instances [2]

It's the second bullet I was referring to initially, which allows
external Prometheus instances to poll the /-/metrics endpoint if
exposed. But to be of any use, those instances would need their IP
addresses whitelisted. Additionally, we'd need a "node exporter" [3]
process running on the same host to provide intel on system-resource
consumption. In the end, this is probably too involved to be worth
anyone's while. So, I guess you can probably just revert whatever change
you made to the configuration. Thanks anyway and please pardon the
distraction.
