Which element from a DLC should TS5 include in base game and what are replacing them for DLC

Basic weather such as rain, thunderstorms, fog, sun etc even if it’s not full seasons and cold and hot weather clothing. I don’t think the holidays should be base game as some people (like myself) may want to change the holidays as they are very Americanised such as the one that is like thanksgiving and the summer one (I don’t remember they are called)
