Digital BW, The Print

One of the digital benefits that I appreciate with every image that I 
convert from color to B&W is the ability to apply a color "contrast 
filter" to adjust the relative gray tones in the image.  If you had a 
monochrome-only sensor, wouldn't you be in a film-like situation, where 
if you want to emphasize or minimize certain colors in the image you 
would have to apply the filter in front of the lens before capturing the 
image?

Cheers,
