What connection do you expect between open source and a set of
applications somehow _having_ to be structured as a library ??

(Yes, of course my Open Source ArgyllCMS Color Management toolset
 has a multitude of headers and libraries that it uses to implement
 its functionality. But being a set of applications, it isn't necessarily
 intended that other applications link to all that.)

You missed profiling. CMM yes, but calibration and profiling and complex
linking, etc. etc. - no - they are user applications. Users
want to be able to pick and choose between such applications, not
be locked into a single implementation. This fosters
competition and innovation, just like any other application
