you change the oil and filter after storage to to get rid of any water/moisture that builds in the engine during storage. water in the oil can lead to oil breakdown.
may seem a waste to you, but it sounds like cheap insurance to me.

I think you misunderstood me. I wasn't suggesting that the old filter be left in place.
What's wrong with the following?
PRE-STORAGE:
- Warm bike, drain oil, remove old filter and discard.
- Do not put in new filter (use old O-rings to prevent leaks)
- Fill bike with fresh oil.
NEXT SPRING:
- Drain storage oil, insert new filter, fill with fresh oil.
- Spend the money you would have used for the filter on a tank of gas and go ride.
You can even briefly run the bike without a filter just to make sure that the clean storage oil gets to the top end.
The filter is there to trap particles in the engine as oil flows through it during operation. If the engine is not running it serves no purpose, right?
