I have to say I really hate it. We've been working hard on

of special cases in the qemu block layer, and this sprinkles them all

I think the problem here is more with the implementation that with the
intention.
I agree that you just can't do this. A patch adding support for a fd:
protocol should touch block/fd.c and nothing else. You can add some
supporting patches that extend the generic block layer to support e.g.
formats that can't reopen. However, if you touch the code of other block
drivers, you're doing it wrong.
