No, there is nothing from scaladsl. It is also the latest version of IntelliJ. IntelliJ decompiles Http as
package akka.http.javadsl;
…
public static Http get(ActorSystem var0) {
return Http$.MODULE$.get(var0);
}
public static Extension get(ActorSystem var0) {
return Http$.MODULE$.get(var0);
}
This is akka-http_2.12 version 10.1.0
