I think that making some spells "exclusive" for specialist wizards or campaign themed PrCs would be fine. Modify Memory fits as a bard spell, but specialist enchanters or Mindbenders would fit the spell concept just fine. Likewise, most of the WuJen spells would fit an "elementalist" PrC just fine.
It seemed in earlier rulesets that even though all these spells existed, not every wizard could just pick and choose which ones to get and just bebop on down to the magic shop and pick them up. Thus, individual spell selection created a big varience in the style and feel of different casters. I guess what I'm trying to say is that in a campaign like this, all the spells could be made just wizard spell (non-exclusive), but their availability would be so limited that gaining access to them would be a major goal for a PC, and therefore "exclusive" to the cult/guild/PrC that has controlled access to them.
