Jujutsu Kaisen: Phantom Parade will be released this year and Junpei was confirmed as a character in it (apparently a villain), even though bigger details about it and what story they plan to tell, if they'll just retell the anime/manga arcs or if there'll be an original story...

Obviously this petition wasn't a motivator of any sorts, but the fact that we'll have more of Junpei either way is a good reason to make this update (at least for me).

I will still try my best to reach them and make the message clear that we'd like to see more of him, but will thank them nonetheless for anything they give us with our jellyfish boy!
