Use sequential colour schemes with discrete data

I get the error message in the title when using sequential and diverging scale_fills with a data set that requires 33 values. I've tried scale_fill_sunset(), scale_fill_iridescent(), and scale_fill_smoothrainbow().

The default ggplot2 scale_fill works fine, as does scale_fill_grey(), so I am expecting the khroma scale_fill functions that are capable of yielding more than the default number of colors to work as well.

User error?

Ah, I see now. The interpolated version expects a continuous scale. Any chance these palettes will be augmented to accept long discrete scales?
