I beg to differ - unless your point is the use of such filters in color photography (in which case you could, but why is the question).
I use Silver Efex Pro to do 95% of my B&W conversions, and the first thing I do is go to the filter section and pass thru the 360 degrees of hues I could have used had I been shooting B&W directly. It's a cheat, and I think back to my brother who, in high school, taught me about saturation, hues and their impact on a desaturated image. But hey, I've got a BS in Computer Science, so I'm going with the software. LOL
That said, understanding what you're looking at in full spectrum color when your intention is grey scale, is a major plus.
