5 years ago Saturn (and Giraffe) are based on ASP.NET Core which means that your more than welcome to use standard ASP.NET Core components, and configuration. Also, from what I can tell, it's standard usage pattern of Giraffe/Saturn users - one of the big selling points of those libraries is integration with ASP.NET Core.
Also, our current helpers for authentication (like use_jwt_authentication and all friends) are using internally ASP.NET Core - we don't invent anything on our own. I can agree that not everything is ported to the fancy Saturn API, but many of the things probably won't ever be ported - just due to share size of ASP.NET Core, and the fact that it's fairly easy to write your own wrapper if necessary (for example https://github.com/SaturnFramework/Saturn/blob/master/src/Saturn.Extensions.HttpSys/Saturn.HttpSys.fs has been contributed by user after he created this implementation in his work project).
And, ofc, I'd be happy to accept PRs adding specific APIs that you think are missing to Saturn.

Rails has Devise, Phoenix has Pow. Authentication/authorization are dangerous wheels for users to reinvent. A centralised system/generator for managing email sign-up, confirmation, reset, multi factor U2F authentication, token/claims based Auth etc. is important. Most of the functionality are already there in ASP.net core, just need to wrap it in a fancier API.
