Why Rendering?

I find it amusing beyond belief how many different terms have been established to express the many different sound practices in film that are created using the exact same basic method. For example, first there was Punctuation, using a specific sound to make something in this film stand out and now we have Rendering, using a specific sound to give us outside knowledge about a character on screen. And ironically, both practices are inevitably achieved through the old and simple practice of added value.

My question is why does it have to be complicated when to the average listener it's as simple as, hey, this sound is here and it works in this way. Rather than the overly long and complicated version of this sound is strategically placed in this exact place in a way that punctuates, in this case imaginary action, and causes a rendered effect resulting in giving us the impression of the character having weight or another specific quality.

I mean I understand the specific differences; it just seems like a new term for something we all already know about since it's a direct result of added value. Not only that, but it’s not as if any of the things heard in this process are really all that entertaining. Creating voices and personalities for cartoons or animations is not exactly a new practice, they’ve been making cartoons since way before I was born and they’ve always used pretty much the same practices, although they do stick out more in Who Framed Roger Rabbit than in a simple Loony Tune’s cartoon because of the live and real props rather than cartoon background for most of it.
