Forward declaration include, on top of declaration include (ClassFwd.h + Class.h)

In Effective C++ (3rd edition), Scott Meyers, in Item 31, suggests that classes should have, on top of their classic Declaration (.h) and Definition (.cpp) files, a Forward Declaration Include File (fwd.h), which class that do not need the full definition can use, instead of forward declaring themselves.

I somewhat see the case for it, but I really don't see this as a viable option... It seems very hard to maintain, rather overkill and hardly necessary.

I can, however, see its use for template forward declarations, which are rather heavy. But for simple classes? It seems to be that it's a pain to maintain and will create a whole lot of almost empty include files that serve a very small purpose... is it worth the hassle?

Here's a example:

// Class.h
class Class
{
    Class();
    ~Class();
};

// ClassFwd.h
class Class;

// Class.cpp
Class::Class()
{
}

Class::~Class()
{
}

My question:

What do you guys think? If this a good practice?

NOTE I am mostly interested in the arguments FOR this practice, to see if I missed something that would make me agree with Scott Meyers.
