Sounds like the "apply --no-add" in the opposite direction ;-) I would find it handy myself, too, though I tend to read my patches after applying to my tree so the postimage is usually an invocation of "less" away for me.

I do not think it is a bad idea to have an option to give only the postimage and another option to give only the preimage. It would also trivially allow people to show the side-by-side diff in GUI.
