To make it effective, you'd only want it to apply to GC pointers. But the type system does not distinguish between GC pointers and other pointers, making such a mode a rather complex implementation problem.

In java-like situations where something like that would see use, I think it would be fair to treat all pointers as gc pointers.

In Java, all pointers are GC pointers. But in D, not very many are. For example, objects on the stack aren't GC pointers.

Objects on the stack aren't pointers at all...

If you have a struct on the stack, and call member functions, you've got pointers. For an array on the stack, taking a slice of it or looping through it with pointers, you've got pointers. For a variable on the stack, passing it by ref to another function, there are pointers.
