If you mean a wrapper similar to this, then that would be a compromise
I can live with:

if [ -t 2 -a ! -e "$HOME/.citation-run" ] ; then
  # Only run if stderr is a terminal (to avoid breaking scripts)
  parallel.real --citation
  touch "$HOME/.citation-run"
parallel.real "$@"

By testing if stderr is redirected this should avoid breaking scripts
(e.g. cron jobs or similar).

To me it would feel similar to a dialog box, where you have to click
"Don't show this again" to continue the first time. This is not that
uncommon in graphical tools, so there is some precedence for this.

I find it less than optimal, but if we can find common ground on that,
it would be a compromise I can live with.
