Why not? They were all fluffy and high after their virtual marriage and devirginization. Throw in a kid they can adopt and their virtual family will be more complete than they dreamed of.

I think Yui was necessary to even the odds against a developer/admin. Beating such people is unlikely, so an exploit accidentally left in is sorely needed.
