Yeah, I don't think this is a real problem; for the reasons you sarcastically mentioned. FFXIV is supposed to be a theme park, if some ride is filled up, go ride another one. Waiting hours to join a Caravan is a waste of time when you could just alternate Caravan/Toto-Rak or Caravan/Darkhold. Content won't get as old as fast that way either. Rewards a pretty well balanced at this point, so you will get the most seals by just going to wherever has the least congestion.
