Well on the negative side sort of, maybe. Generally, I'd say the srgb 
decode equation mangles values outside the zero to one range making it 
hard to control - to get what you want and too easy to not get what you 
want.

Yes. I think it better users make use of rgb* keywords, where they want 
to work with values outside the 0-1 range so povr forces this.
