Re: [csswg-drafts] [css-color] "device-cmyk" restrictions are counter-productive (#2022)

Coming back to this, and specifically the idea that device-cmyk should be defined with an `@color-profile` in the user-agent stylesheet, this is now slightly complicated by the otherwise good resolution to https://github.com/w3c/csswg-drafts/issues/4654 which put predefined colorspaces and author-defined colorspaces into two disjoint groups, the latter using the new `dashed-ident` production.

However, the general idea still has merit and would be an improvement over the rather handwavy prose that sometimes magically turns a device-dependent formulation into an actual color.

On a related note there are now [some examples in the spec about using `color()` with CMYK](https://drafts.csswg.org/css-color-4/Overview.html#cal-cmyk), with both FOGRA (Europe, UK) and SWOP (US).  Which led me once again to the idea if defining how device-cmyk works in a similar manner.
