Because actually we're implement/develop some features based on mainline kernel and sometimes the features are not valid on all of Exynos4 or Exynos5. Even though they are not in mainline, for mass product it's true that Samsung needs to do it. It's another thing we have a plan for them or not. So in my opinion, basically consolidation something is usually good but it's not always good so we need to provide a way to use one of both.
