Completely agree with you...tried suggesting it with a luke warm response. Peronally I do use it on Wiki sites (with my own little modifications).
I tried to get the MTF as a seperate CKS project, but there weren't any real responses for it.
I will give a little plug though to the ARF (one of my other projects) (www.codeplex.com/arf), this is mainly aimed at MOSS websites but 95% of the functionality is developed purely for WSS and will work for Blog,
Wiki and discussion sites.
Also I am just about the start a project with an Enterprise client which is going to need the MTF with Wikis and Discussions...so you never know.
