Directly emitting metrics using OTLP instead of having the OTel receiver scrape the metrics endpoint is interesting. I never made that move because the Prometheus metrics endpoint works and is so simple, and it's what most projects (eg kubernetes) use.

A long time ago, I introduced dogstatsd at Airbnb. We had already been using vanilla statsd (with no tag support -- cardinality lived in the metric name!) and this was a low cost migration. More than a decade later, I'm assuming it was difficult to track down and refactor all the places that statsd calls were emitted and using OTLP was an easier route. This is a great example of how technical decisions compound over time.
