I’m pretty sure what was already the case was that you needed Plex pass to use the Plex hosted relay for when port forwarding failed when behind Nat. This seems to apply to all remote streaming, including when you’re directly connected through port forwarding or a reverse proxy and not costing Plex anything to transfer your traffic.
I give all my friends the choice between Plex and jellyfin (I run both containers side by side pointed to the same media folders) and they all invariably choose Plex. I think it has a lot to do with the jellyfin UI, and I think an overhaul like jellyfin-vue or something that looks like findroid needs to happen in order for jellyfin to really appeal to regular people.
