Hear, hear! I find it very tiresome for so many people to complain so bitterly about the few projects that really seem to be improving and revitalizing the Linux ecosystem. Pottering and Packard seem to be some of the few people who are willing to take on the challenge of improving what has come before instead of casting it in bronze as a museum piece. In this specific case it is particularly ironic because the Wayland developers also seem to be the X developers and if anything Wayland is X12.
Wayland is heavily informed by what does and doesn't work in X by the people who know it most intimately. As you say some people are just assuming the very worst and doing nothing but complain but the developers they are complaining are wrong and the developers they are holding up as right are _the_same_people_!
