The Otel spec does give leeway for language-specific details, and the SDKs are not as uniform as you'd expect (ex. Java's agent configuration is very different from Node's auto instrumentation). I'm not denying that there's SDK specs to adhere to, but the abstraction complexity in Otel is really from the amount of flexibility they've tried to build into the SDK for better or for worse.

The flexibility benefits vendors (I work for HyperDX, based on otel) - as it allows for a lot of points of extensibility to build a better experience for end users by extending the vanilla SDK functionality. However, it creates a lot of overhead for end-users trying to adopt the "vanilla" SDKs out of the box as there's 5 layers of abstractions that need to be understood before getting things started (which is bad!)

I've only seen the DX of Otel improve over time across the ecosystems they support - so I suspect we'll get there soon enough.
