I use memory profiling with Go and it is indeed very useful. I think that whatever Go already provides is enough, but I guess Uptrace could try to automate some things and/or provide some fancy UI.

But I find CPU profiling a lot less useful, because production profiles tend to be too broad and it is hard to make sense from them, for example, Uptrace profile mostly consists of memory allocations and network calls.

So I would not say that CPU profiling is superior/better/can replace tracing.

Tracing is a piece of the puzzle and necessary. Profiling occupies a different part of the monitoring ecosystem.
