I believe the major issue was quality control? As in he has to be there to overwatch and make sure things are going swimmingly. So quality control and quality assurance. What helps here is that Matsuno has taken an interest in the project to some degree. While he may not be on the payroll - or he may be, I'm unsure, does anyone know if he's officially on payroll for Shadow Bringers? But anyway, quality control and quality assurance can honestly be overseen by him as the original creator. This only works for mViera however.

Either way, Matsuno's interest is very endearing that he's looking over his 'baby' to some degree. I'm curious to see if his vision of them is made official.
