Yes, Alastair is documented as saying they discontinued hollow (i.e. no truss rod) mechs because customers wanted the option to adjust neck relief which the two way truss rod in his guitars can do. Like most above I'd say a truss rod is not required in a CF guitar in the same way as in a tone wood guitar but I do like the ability to tweak the setup that my X7's truss rod allows.

My Eastwood Custom was built with a stainless steel bar in place of the truss rod (a bit of an experiment which I was an active party to). Brian did rebuild the neck a few years later to install a truss rod as it was gradually moving backwards. We decided that this was because the ebony FB was changing at a different rate to the maple neck as the guitar aged. It has been fine ever since.
