> Seriously go look at modern Spring's flux stuff, it's all there minus the type classes.

I don't use spring or plan to use it. Not quite sure why it needs to be looked up. What are you trying to say?

I'm postulating that any modern CRUD app framework has Monads, Monoids, and other categorically inspired structure, even if they don't call it that or have a way to abstract over it.

If it isn't called that and doesn't have a way to abstract over it, there's a very good chance that many of the logical Monads/Applicatives/Monoids/etc. are subtly not implemented as those things, resulting in equally subtle bugs.
