Hey now...its not an unintended "feature"...it was my idea and a damn good
one at that :-)  I felt it was important to have an easy way to have the
same shape and amplitude of curve do the same thing across various inks.
Before ink limits it was much more difficult to know how to set the
amplitudes of the various ink curves relative to each other...at least in my
opinion.  The feature also allows for those subtle tweaks that are
frequently necessary when you move from one paper to the next.  Paul Roark
has frequently reported problems with mottling with Museo using the Epson
driver.  IJC makes childs play of this...because it was a simple ink limit
problem in the midtones. The ease which you can tweak profiles for different
papers and really tune them in perfectly is one of the most powerful
features of the program and makes it much easier to use than RGB workflows
with the Epson driver.
