I'd recommend trying it out today. In 2021, very few things in OTel were GA and there wasn't nearly as much automatic instrumentation. One of the reasons why you had to dive into the spec was because there was also very little documentation, too, indicative of a heavily in-progress project. All of these things are now different.

I'll be happy to take your word that some implementation issues are now improved, but things like "overengineered" and "way to complex for what it needs to do" really are foundational, and can't just be "fixed" without starting from scratch (and presumably this is all by design in the first place).

  That's fair. I find that to be a bit subjective anyways, so I don't have much to comment on there. Most languages are pretty lightweight. For example, initializing instrumentation packages and creating some custom instrumentation in Python is very lightweight. Golang is far more verbose, though. I see that as part and parcel of different cultures for different languages, though (I've always loved the brevity of Python API design and disliked the verbosity of Go API design).

One of the main reasons I became disillusioned with OTel was that the project treated "automatic instrumentation" as a core assumption and design goal for all supported languages, regardless of any language-specific idioms or constraints. I'm not an expert in every language, but I am an expert in a few, and this just isn't something that you can assume. Languages like Go deliberately do not provide the sorts of features needed to support "automatic instrumentation" in this sense. You have to fold those concerns into the design of the program itself, via modules or packages which authors explicitly opt-in to at the source level. I completely understand the enormous value of a single, cross-language, cross-backend set of abstractions and patterns for automatic instrumentation. But (IMO and IME) current technology makes that goal mutually exclusive with performance requirements at any non-trivial scale. You have to specialize -- by language, by access pattern (metrics, logs, etc.), by concrete system (backend), and so on -- to get any kind of reasonable user experience.
