Please see my longer response about why doing this _in_ CMYK is
usually wrong, premature optimization by using device dependendt color
spaces if the result might go to many different printers, profiles

Some of these are true, and GIMP is working towards lifting some of
these limitations by migrating to GEGL.

These concepts do transfer to GIMP, and if one is generally empowering
students with the ability to do manipulation on images.. teaching them
how to do it with GIMP gives them both a skill and an option of a tool
they can use without a fee; as well as have the freedom to improve in
the other ways free software does. Pointing out that some things work
better in Photoshop doesn't seem constructive in this discussion.
