We're not actually talking about that though? We're talking about PC death and TPKs.
Ultimately doesn't it come down to: does death of PCs (including an up to TPKs) add to the enjoyment of the game? The rest is IMHO opinion semantics. If I and my group agree that death should be rare but possible, then I'm going to do what I can to fulfill that goal of the group. If I and my group decide that death lurks around every corner and no one is safe, then so be it.
As long as the group has an understanding, I don't see what the issue is.
