Thats why I said possible updates. It is more likely they got it from feedback. Japan and Taipei do not list their actual approval criteria but from feedback from others we know what's needed.
I do not think a blanket new requirement update has been made available. They are going by feedback from applicants, possible embassy website updates etc. Not sure it is many though.
