Not sure what you compare it to. Even finding declaration was never an easy job in C, and definition can be anywhere in the source tree. In D symbols are at least tied to modules, so you can look only in the respective module, this never worked for C though.
But that's just it. With UFCS, the function no longer needs to be in the same module as the class/struct to which it is referring. In fact, that is the whole point.
In the relevant C++ proposal, at least you can be sure that there is at most one such function. Otherwise, the linker will complain (namespaces notwithstanding). In D, you can't even say that. There may be three (or three thousand) such functions, each in its own module, and until/unless you try to import two such modules, you won't even notice it.
