But why gen a new id if someone passes you an id? Just use the supplied id in the called srvc.
This is certainly disputable territory, but the main motivation is that depending on service architecture, a single incoming request can balloon out into a full tree of backend requests because requests can map 1:N between any two components. Assigning every request in every component a unique ID allows any particular request to be isolated, while still allowing the any subsection of the tree to be viewed all at once.
Visually, this might look something like this:
Component 1 Component 2 Component 3
