No, the forwarding isn't being abused. You're trying to solve the
problem of spammers forging addresses, remember? Forwarding isn't
actually the problem you started with. It's just that forwarding is
indistinguishable from 'forgery' in your proposed solution to the
original problem.
But there are other solutions to the original problem which don't have
this problem with forwarding. Thus, the 'cheap forwarding' of which you
speak does not have to be 'closed'.
If changes _have_ to be made, you'll find that people support them;
witness the fairly widespread support for closing open relays, as you
pointed out. The difference here is that it _isn't_ actually necessary
to break forwarding; there are multiple alternative solutions to the
problem of forgery, which don't break forwarding.
