I had issues using gnu parallel in the past because of --will-cite. I ended up not using it.

There is a Rust clone[0], that works seamlessly for my -- arguably simple -- use cases.

What problems arose?

I usually just run --citation once on a new system, and never see the notice again, and I have never had the notice cause any problems as it only shows if the output is to the screen.
