I buy these, and I understand why they apply to "git diff" and not GNU diff.

I don't see a use-case where a command produces old1 new1 old2 new2, but if there is one, then "| xargs -n 2 diff" is the solution. You don't need your patch.

I don't see how, if you specify explicitely the pairs (old, new). You may have such benefit if you let the command-line express "here's a bunch of old files, and a bunch of new ones", but not with your proposed syntax.
