GRACOL 2006 versus newer icc profiles

Today I was wondering why the GRACOL 2006 is still included, yet the GRACOL 2013 is in popular use in the real-world. Why isn't that included in the box?

Are their other coated and uncoated profiles that have become more popular in recent years?

It's been a while since I paid much attention to general 4C profiles and such, but my impression (that's a joke, son, a joke) is that they tend to have very long lifespans, and/or that newer ones are adopted slowly across the industry,.

Process color is, after all, an extremely mature industry, and doesn't need to rejigger everything on an annual basis. Once a major build of a press is put into operation, the color profile it uses tends to be stable until some major overhaul.

Or so I think I kind of sorta understand it.
