Even without being able to compile it I've successfully used their source dumps to debug problems in my code quite a few times (and occasionally find bugs in their code which I have to work around). Having code with comments to read is a huge step up from having to rely on decompilers.
(Quick note for others that my GP comment originally contained a paragraph about the stuff Apple does open source. I edited this out because I felt it was beside the point.)
