Changing the gamerule maxEntityCramming seems to only have effect in the overworld, not in the nether and The End. In a single player world this works for all world. I verified in level.dat that the value was actually changed. I have restarted the server, which also didn't make a difference. I looked through the config files of both the plugins and bukkit(.yml), but nothing that seems to have anything to do with the entity cramming. This seems to be a Bukkit thing. Am I missing a config somewhere? Is this a bug?
