Considering that CO's 50% EQM policies effectively discourage using Skyteam (but not AS) partners I would tend to agree. CO is clearly not very interested in making the Skyteam partnership very beneficial for Elite flyers - instead taking measures to make using parters much more of a "last resort" option. Adding DL upgrade reciprocity would just make DL flights more attractive to CO Elites which I doubt CO wants any part of.
