Sorry if I'm not using the right terminology here. By layers, I'm talking about the different places from where you're emitting spans - like in your example, the UI, prompt-embedding, vector-store and context-encoding. What I was curious about was two-fold - one whether there are use-cases that make sense to have experimentation of the kind that allows a user to swap out a particular step in that stack - and second about making use of context propagation like baggage enables in OTel.
