Sean, I know what you mean about not wanting to to add something new like this. I have a patch in gerrit where I try to use it here:
http://review.source.kitware.com/#/c/10209/1/Modules/Core/Common/src/itkImageRegionSplitterMultidimensional.cxx And the Windows compilers generated errors: http://open.cdash.org/viewBuildError.php?buildid=2840629 So it does not appear to be compatible with VS 2008. For just this one patch I am not sure if it is worth it as well. Where this may also be quite useful in with the VectorImage's VariableLength pixel type. The needed malloc for the temporaries is undesirable and in multi-threaded code is a bit of a bottle neck. I think this may be a very useful tool for tight loops in those situations too, but I have not looked into it.
