and the wiki has documentation about a mirror function, remove_building. CK2 has a function in its events to add and remove buildings, with this one being the one that adds shipyards for the Norse. Now, the way this can be implemented is actually rather easy. These will act as a supporting gate to go alongside the existing technology system the population can be well educated by medieval standards, but if the thing they need hasn't been invented yet, you're not suddenly going to be able to build up a cathedral when your people don't know what a rib vault is even if they have the know how to build it. The number one source of education in a province will be temple holdings, which (much like in our timeline) serve as temple schools to provide education for the "masses" and will be able to host a large number of improvements such as seminaries, cathedral and monastery schools and, later, universities. In a way, it sort of acts as a development "wall", but will also have meaningful effects in the kind of events that will fire in the province itself - things like, say, business success will be more likely in a province where there is a well educated population to support this. Basically, the educational level of the province will act as a general barrier for the complexity of buildings that can be built in the province, symbolizing the amount of higher level educated professionals in the province - skilled craftsmen and architects, literate clerks and accountants, that kind of thing.
