CMYK is not so important now, but Lab IS.

Even last Dan Margulis' books are about Lab and not CMYK, like older ones.

And looks like no native Lab (or CMYK, for that matter) in 3.0: data is still sRGB, and converted before and after tools.

It is bad.

Lab has much more wide gamut that sRGB.

I think that was a typo in the article - GIMP is now "anyRGB". The color profile is associated with the RGB values, so you can load, work in, and export AdobeRGB, AppleRGB, etc.

We also load palettes (ASE, ACO, etc) in CMYK, CIE Lab, etc. It's true we don't have a dedicated CMYK/LAB mode yet, but 3.0's color management work laid the foundation to implement this much easier in a future release.
