> OTel _does_ prevent lock-in on the agent side (making it easier to switch vendors) with open source components and consistent schemas, but OTel doesn't enable you to do anything that you couldn't do before with a specific vendor

This is exactly the reason why we are moving away from NewRelic's SDK to an OpenTelemetry SDK (even though we are still using NewRelic to ingest everything). If (more like when) we decide to switch vendors, it will be much easier to do so.
