There should be some method by which players can check the techs that have been researched for a city in order to ascertain whether that is a region they want to purchase a plot. Currently, the only way appears to be having access to a crafting station and learning the recipe in order to see the message that the tech hasn't been researched. I'm not really up on the siege mechanics or whether having that information public would create higher risk of conflict, but there has to be a happy medium here.
