The problem with a technology only being required as OR prerequisites means that you can theoretically skip the tech if you research all the other OR's. Remember why I asked to change Banking? You could skip Usury forever because the only place it was required was an OR tech for Banking. We need to have at least one AND for Reincarnation and Resurrection for them to be completely woven into the tree.
See that is something I disagree with. The things that the tech gives you should be enough that you wont skip it. This is why I wanted camel/horse/elephant domestication to all be semi dead end techs you only needing one to get through the tree. Because those techs are useless in themselves if you don't have access to that resource. However they are very useful in their own right if you do have multiple riding animal resources.
