I fully appreciate the "doing it for the fun of it" mentality. Am I wrong in assuming that is the "why" behind this project?

I have used OS X full time for 7 years now, and I love it, but I never thought the kernel had much to recommend it.

My interest in having a running Darwin system is the ability to build OSX things on an openly licensed platform. I know that it is permissible to virtualize OSX on top of OSX, but even that is a PITA and more so in a TeamCity/jenkins/etc setup

Giving what the mingw project has contributed to being able to build Windows binaries on Linux, I'm pretty sure it would be possible to do something similar for OSX, but since so much of it is already open source, it seems a waste to discard the exact code that OSX is running
