It's
definitely important for product photography - catalogues, advertising, online product configuration choices, fine art reproduction etc...
Imagine selecting the colour for your new car then finding it's a completely different shade upon delivery?

That's a nice idea, but adjusting each colour typically alters other related colours (e.g. adjust blues, and your purples change... tweak the purples, and now your pinks look wrong).
When I set out to emulate the K10D's colour reproduction in Lightroom using K-3 raw files, I started with the primary red, green and blue channels - which got me in the ball park - then went on to adjust each colour individually. It took me many, many attempts and revisions to get it close, and even then it wasn't 100% accurate. In truth, 100% accuracy wasn't my goal and didn't matter in that application, but I mention it as an example of how difficult it is to achieve reasonable colour accuracy when adjustment of each colour affects the others.
For general photography, I don't believe it's important, and that's why I don't use chart-matched colour profiles any more. But there are applications where it
can matter...
