The team behind the Rust efforts for Open Telemetry have paused development of the prometheus exporter until the SDK and API reached 1.0. As that can still be a while before that happens, it is probably best that for now (and perhaps "forever") that we replace the current prometheus exporter with https://crates.io/crates/opentelemetry-otlp.
This still allows you to use prometheus, so for the user there should be little difference. It might in fact also just be the better appraoch.
