Still sounds like a reasonable use-case anyway. I could see it being useful for library providers too, who want to hide some things in the external interface, though I don't know of any concrete examples.

If we choose to support this (and I'm happy to +1 it), then I think it should only be a long-form switch, with no short-form equivalent. That's because there's a much higher chance of something being added to GNU objcopy in the future with a short alias that causes a clash than for a long-form version.
