Probably the most interesting part of this latest dev diary for me was the addition of coal as a latent resource, only available with enough development and institutions. This strikes me as something that has a lot of potential for modding. Some cases that come to mind: iron as a latent resource in the late Bronze Age; New World crops being cultivated in the Old World in EU4's timeline; oil in Victoria's timeline; major inventions like paper, glass, or steel in their respective eras.
What do you guys have in mind for latent resources?
