maybe you are right.

But my point is (well, always was) to chop off the server internal 
modules in parts so we can have a lean implementation for different 
purposes and cover everyone's desires. The testing and conformance could 
be stressed in a different way, but not just compiling and forcing 
developers to use the thing.

Actually, by implementation of X11 we can pick all client libraries, 
headers, the server itself and drivers. So what motivated you to break 
them in pieces, when you started the autotools conversion?
