I got the same feeling. They decided to address their decision not to base off of Wayland, but all I read was a convincing reason to fork off of what Wayland is doing. I wish they would have given the real reason for their decision, right now it just smells like NIH.

Why don't you address the specific technical reasons given in TFA?

None of those few reasons are particularity compelling and they could be addressed with Wayland just as well.
