Internet co holds their license so they aren't Yamaha vocaloids... It makes things easy and difficult at the same time as we know Internet co does update their vocals. However, they don't always rush to update... Ryuto is an example as he originally wasn't to get a update but did only for Gachapin's anniversary 40th.

with professional vocalists though, getting them into the recording studio is difficult so you may get just a straight up "add gwl" moment like Gackpoid V4.
