I've used Otel quite a bit (in JVM systems) and honestly didn't know it did more than tracing.

That said, I think this rot comes from the commercial side of the sector -- if you're a successful startup with one product (e.g. graphing counters), then your investors are going to start beating you up about why don't you expand into other adjacent product areas (e.g. tracing). Repeat previous sentence reversed. And so you get Grafana, New Relic, et al). OpenTelemetry is just mirroring that arrangement.
