My experience with soft landings is that it is often on a case by case basis. For example, if you've been Gold for multiple years and then you do not qualify, the airline may "comp" you status for one-year.
Also, many airlines are responsive if you write to them, can prove/demonstrate your travel over the next 12-months.
I think because the airline frequent flyer programs are now so large, the loyalty folks probably don't spend enough time on this factor. I know I would always write to the airline if I thought I was not going to qualify and would recommend that you do this, if you are in this position.
