Ok, thanks for the quick replies.
I know that it does a little bit more, but surely there exists several use cases where "a little bit more" is not necessary, in my case I have the authentication service in a Play application, so what you say makes sense, but i have more services that use this service for authentication, and these services already have the token and communicate between them through an actors in an akka cluster. There is no requirement for a statefull token.
When u say "The new framework agnostic", are u referring to version 5? And will this be possible in then?
I considered using, for example, "jwt-scala" or "authentikat-jwt" to work around this, but i would prefer to use silhouette.
