Your response raises some intersting points and sounds reasonable. But also kind of too dreamlike. Is it possible to seamlessly integrate a user managment system in f# into existing c# code? I guess, it's not that simple. It also reminds me of an experience I had in a former job with C++. There was a very, very experienced senior who wrote a very clever library which allowed us to add varous metadata to domain objects in a a compile-time checked, type-safe and very performant way. When the guy left, everything went downhill and the code from then on was regarded as mysterious black box noone dared to touch. Somehow I am reminded if this when I read about 'magic' solutions in FP. Is it possible to reach a state with FP where seeing through it all gets too troublesome?
