K-interpolated YoY optionlet volatility.
The stripper provides curves in the T direction along each K. We don't know whether this is interpolating or fitting in the T direction. Our K direction interpolations are not model fitting.
An alternative design would be a FittedYoYOptionletVolatilitySurface taking a model, e.g. SABR in the interest rate world. This could use the same stripping in the T direction along each K.
