I am aware of arxiv-citation, I couldn’t get it to work, perhaps I did something wrong.

Feel free to open an issue in the usual places.

I posted about whipping up something like this here; maybe it’s what you’re looking for

I don’t think this’ll be easy. The Rust related PR was closed a while ago, with only a small note added to the docs somewhere. I created an issue about the Haskell behaviour, but that has not seen much activity in a while.

If someone could point me into a direction on where to upstream this, I would be glad :)
