I'd like to strip the many years of bottom paint from my hull and was thinking if I did it in the fall while it's still "nice" all I'd have to do in the spring is paint. Is there any harm in leaving the bare gelcoat bottom exposed over the winter?
You do not want to seal any absorbed water in with the paint. Best practices say you should strip during the beginning of a hot spell and let the hull bake out as long as you can before painting. Realistically, the humidity in winter is very low, if you have no blisters now and protect the hull from getting wet for prolonged periods it will probably not hurt anything.

Outside, it's high enough to create frost, snow, sleet, rain, ice, etc. Very little of those things will affect the bottom--they will collect on deck. The existing bottom paint is not really protecting from moisture penetration, anyway--especially if it's separating from the gelcoat. Go ahead and take it off. But if you're using a stripper (which is safer to health and the environment than sanding or blasting), temperature can affect its effectiveness. (Check the label.)
