It shouldn't be something they feel they have to include in each new IP. If it doesn't fit within the frame-work of a game then it shouldn't be there. I don't think anyone would have a problem with that, as long as it's not something that's being removed from an existing franchise.
Personally, I like the extra layer of depth relationships add to a game like Dragon Age, which is based around having a party. It was also an enjoyable addition to their Star Wars MMO.
