I noticed some recent changes as well.
Has the coin name been inside the job name before? Like DOG_something or MOO_something? :-)
I also noticed this recently, although only once I started to use cgminer 3.1.1. Personally, I don't think it makes much of a difference whether the names are there or not since it isn't too hard to determine what is being mined by looking at the reported network difficulty in cgminer.
