After running through twenty different ways to rephrase "Append" I settled on "Vocalists with voicebank upgrades". This way there doesn't need to be more categories that further settles on who was updated or has additional. If I did that it would simply be Hatsune and the Kagamines.

Anyway, while it's risky I included Big Al into the section due to his voice provider being switched and his vocals becoming more polished after the fact.
