As I understand it, it is against one of fundamental D principles: structs are value types where any copy can be used in place of any other.

I expect there are examples where even Phobos violates it but the struct documentation still says so: "A struct is defined to not have an identity; that is, the implementation is free to make bit copies of the struct as convenient."

Disallowing automatic copying and providing a function comes to mind.
