I'm guessing w/in a few months Google launches a G+ integration with search that lets you reference your contacts in search queries using the + operator.
(Am obviously joking, but I agree with your sentiment that G+ integration does seem to be... going quickly; I can understand why from a business POV though)
It seems that this is just inviting ill will for no reason. At least if they did both at the same time, they would be able to say "But we did this other new thing instead! Isn't it neat?!"
