Having read the rest of the article, I can now add that according to Graber the new product is specifically aimed at corporate clients who have downgraded from C to Y. It is now up to them to play ball, Graber says.

The travel managers of two large Dutch companies interviewed in the same article expressed their doubts about the new product. A major objection was that Comfort Economy does not book into its own fare bucket, and can therefore not (yet) be reserved through regular GRS reservation systems. This increases the administrative burden, and makes it harder to stick to the company travel policy in employees "upgrade" at check-in and claim expenses afterwards. In one of the companies the travel policy was so restrictive that CE upgrades would require management approval.
