Hot weather & cold weather wear coming to base?

I want to guess it's really just for future convenience in lieu of how to make the whole seasonal wear work without a complete overhaul of every CAS item and also for easy use with future packs that have these new categories in mind. I'd find it extremely difficult to code every single piece of CAS clothing with warmth ratings or something since it's been 4 years worth of content in there and find it an easy resolution to just tie it to new hot/cold clothing categories instead.
