https://github.com/EtchJetty/MEGIDOBeta/blob/master/Fonts/FontSizes.remap FontSizes.remap is used for registering XNB files to the game, I think. (Not completely sure.) It uses a variation on Json that includes comments - having a way to import without conflict might be nice for future mods that both wish to register their own fonts.
