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).
