 **[1]:** Instrumentations SHOULD require an explicit configuration of which headers are to be captured. Including all request headers can be a security risk - explicit configuration helps avoid leaking sensitive information.
 The `User-Agent` header is already captured in the `user_agent.original` attribute. Users MAY explicitly configure instrumentations to capture them even though it is not recommended.
