I assume you know it really is possible, right? (in URL parameters - with certain limitations about size if I remember correctly... or did just IE choke at 2048 bytes? I forget...) I am not arguing you should use GET instead of what should clearly be a POST, but saying it is not possible is IMHO misleading. And there are sometimes valid business reasons to use (invalid) technical solutions.
I understand your point, but neither extreme (always staying with legacy / always rebuilding) is particularly good.
