The patch came in barely working (not compiling on all platforms) and hacked together. Anyone who's worked on a long lived code base knows good architecture is important. They explained what was wrong and how to architect it cleanly. It's not the responsibility of the MAME developers to do his work for him. They also reasonably discussed the utility of supporting his niche closed hardware. Remember once the code is in tree it's their responsibility.
