I think the shikon shard thing is the limiting factor to go with, there - if you only allow major characters to have one, then whoever is forming your hero cast governing group will be able to limit what goes through pretty well. Besides, if they let it become common knowledge on the future side of the well that there was a path to the past there, THEY'D get trampled under the heel of government exploitation as well, and some charactrers at least are smart enough to realise that and persuede most of the others (Nabiki springs to mind as the immeiately obvious one).
