Check out the [OpenMetrics project](https://openmetrics.io/) for the future of
the data model and exposition format used by Prometheus and others.

Note, though, that in an ironic twist of fate, the protobuf-based exposition
format got revived to ease the implementation of experimental support for
native histograms in Prometheus. Therefore, starting with v2.40.0, the
Prometheus server is again capable of ingesting the protobuf-based exposition
format (if the respective feature flag is enabled). Eventually, native
histogram support will be added in some form to OpenMetrics, too.
