Usecase for host level api (Akka http client)

Hello,

This discussion is regarding Akka HTTP’s client side functionality.

Request level api is built on top of host level api where connection flow is materialized for each request. Only difference that we can guess is that in host level api we can configure different connection pool settings for each host. Configuring different connection pool settings for different host is not possible in request level api.

Is this the only use case when one can go for host level api instead of request level api?
