I posted some explanations on the matter in Japanese village pump and solicited opinions for those who prefer communicating in Japanese.
Here is an input from Gombe, (as I understood).
Gombe thinks that while it's a little disappointing that article count doesn't really increase, counting comma is not totally unacceptable because the main focus of the project is elsewhere anyway.
As an alternative, Gombe suggested counting more-than-two-paragraph could be good.
---- By the way, for those who are interested, Japanese wikipedia is like this right now:
3762 pages 296 counted as articles distribution of file-sizes in article namespace 7 = 0 bytes 127 < 50bytes 270 < 100bytes 812 < 200 1132 < 300
