I know i'm in a significant minority, but I care a great deal what goes in processed pork products (or rather, my gut cares). I've yet to pin down which "preservative" commonly used in pork/pork-like products I'm allergic to, but I have a serious problem with even Kosher Hot dogs.

Basically, if its not fresh homemade bratwurst or sausage, I just can't eat it.

I'm sure that, if these methods continue to become more viable than their livestock counterparts, then the need to use at least some preservatives will decrease... hopefully.
