Isn't that what some people are actually doing be selecting say Velvia and Ciba? THey are using the materials available to best present an artistic interpretaion of the landscape that is before them.
I believe that Chris Burkett that I mentioned above, (who I understand to be a deeply religious person - he was going to be a monk at one point in his life), has used masking with Ciba to intensify selected colors in his prints. While Burkett has the skills and finesse to not blow out and oversaturate parts of his prints, he's doing just as you said above.
