Gordon,
When I made/committed the start of the cart.module upgrade, I took a long look at the whole checkout process, and eventually decided that it was simply way beyond me. I think this may well be one of the most complex multi-part forms in any 4.7 module, so we're going to need help from the biggest formAPI gurus around.
One resource that may be of help: did you catch merlinofchaos's multi-part form solution which he blogged recently?

I don't know if this sessions-based approach will actually work for the cart module, but it's worth looking into.
I am not too sure, but I did see that there has been some work on sessions and anonymous users will not get a full session so that may store this from working.
I think at this stage that this is beynd the current formsapi. I think what needs to happen is a method in the formapi so that you can throw an error in which you can tell the form process to build a completely new form and $POST will be reset.
anonymous users can get a full session at any time someone sets the $_SESSION variable for them. It means, though, that the optimizations for anonymous users without sessions disappear when this form is used. For something like the cart, I think that is perfectly fine.
