Since clues is designed around strict context-bound propagation of values, it runs across some hiccups which other packages tend to solve with global instances. Namely, patterns where a main func initializes clients (such as otel) but processes requests with a separate context, as is traditional with http servers.
The Inherit(from, to) func gives callers a plug which they can use to propagate clients from their initialized context into individual request-bound contexts, which can be utilized in a http handler middleware.
