The main problem with that patch is that we don't really know if it actually works well. We've accepted a similar patch for ciso support a few months ago and it turned out to work fine for many games but others would fail for no apparent reason without anyone trying to fix it.
EDIT: Looking over the patch, it looks more like a quick'n dirty patch rather than something which meets Dolphin's code quality standards (... which aren't really all that high, but no reason to include more hacky code). E.g. there's a line which reads "HACKS AHOY!" in the patch
