You have some good points that all should remember. With Mother Nature going crazy, we have no idea of what might be coming down the road. I'd say make those quilts, put them in plastic or something to prevent moths, and if not used, keep them, just in case.
When DH passed, I gave the kids almost all of our camping gear (at age almost 78 I'm not going to want to go camping again) but I did keep one mummy sleeping bag, just in case. And I do have warm quilts, just in case and because I love them. And have made warm ones for family young ones, big enough for them to use as couch throws to keep warm while watching TV.
Sometimes in plain rainy weather some of our electrical wires break, and we're without warmth for hours, so I'm making myself one (a couch throw) now. And will either sew, tie or snap the bottom together to keep my cold feet warmer.
