The benefit would be that I could use the state of the global to
determine if this was the first time it had been initialized and run
some setup code. The natural state of certain globals is empty, so I
couldn't simply test for that. If I were coding from scratch I would
just work around this, but I am porting business logic from another
dev environment. They use this extensively.

On the other hand, just declaring a global automatically
initializes it to empty, so maybe that's enough for the original
poster. I don't see too much difference between empty and NULL;
there's a slight difference but probably not one that would matter
too much in most cases.
