+/// keeping a single global reqwest::Client in the reqwest backend, to simplify
+/// the way we abstract away from these.
+///
+/// In the future, should we need it, we might be able to add a CustomClient type
+/// with custom settings. In the reqwest backend this would store a Client, and
+/// in the concept-fetch backend it would only store the settings, and populate
+/// things on the fly.
