This is really exciting since the Otel collector already supports Datadog tracing, adding metrics will cover the big two signals that make it hard for most teams to shift from DD's walled garden. I suspect this will really ease the migration path from closed standards to open for a whole swath of companies now.
Hopefully the PRs get upstreamed quickly without any opposition from Datadog unlike last time.
std disclaimer: I'm building oss obs for hyperdx, so I have a clear horse in the race for companies adopting open standards, just like grafana.
