Early on in Professional Photoshop (v.4 -- the one I 
read, way back) Dan explains how he had a color-blind 
friend doing color corrections, using the basic 
principles/goals that he outlines.  This friend 
made a few errors, but in fact most of his corrections 
yielded beautiful results, which do appear in the book.

Dan insists that you could use a monochrome monitor 
to do color corrections.  Now, I admit I haven't 
tried that.  But it is quite a provocative claim, 
and follows logically from Dan's numerical approach.

I don't remember Dan using the word "accuracy" anywhere 
in that book.  Ie., color accuracy, per se, isn't held 
up as a major goal.  Speaking for myself: my goal is to 
produce pleasing, believable photographs, of subjects 
I've chosen.  Matching colors to Pantone swatches is 
nowhere on my list of priorities.

In this regard, I reserve for my own color work the 
freedom that BW photographers enjoy, where nobody 
argues about the "accuracy" of the rendition.  It's 
inherently subjective.

So, maybe it's not for everybody.  If you have clients 
with specific demands for color accuracy, you may need to 
go with the more mainstream, ICC-sanctioned methods.
