Does this seem like an option worth adding to the PostScript terminal?

That is, in PostScript we have image output that can be either indexed 
or a colorimage. The obvious connection is palette-based images are 
indexed, RGB images are colorimage. Would it be worthwhile to have an 
option that forces the type of output image to either always indexed or 
always colorimage? The immediate motivation here is a work-around for a 
problem that may or may not be the terminal drivers fault. I guess that 
may be reason enough, but is there a more legitimate reason for doing this?

It would be easy enough I think to generate a color image from an 
indexed image. Vice-versa might not work so well. The palette would be 
very large. So maybe an option of "indexed" for "set term postscript". 
I've no strong opinion... although I'd sort of like to stick with 
palette being indexed, RGB being color image.
