If it's blended fine, like other veggies, I think it would be ok. But even if not, it's good fiber. And you don't have to get fancy with the cooking unless you want to. Just nuke it in the microwave for the few minutes.
I personally have had no problems with pork. I figure if my dogs eat dead animals they find in the yard, commercially-raised and processed pork can't possibly be that bad.
Mine crunch the bones easily, but I could see them being a problem for smaller dogs. They're pretty thick and heavy. Maybe you can feed pork meat to smaller dogs, but not necessarily the bones. I wish DanL would chime in here about his experiences feeding RMB to his pug.
I'm not overly concerned with the bacteria -- I have the same thoughts as you do. I'm sure they've eaten worse.
My main concern was them being able to eat the actual bone and break it down. I know that they can often have some pretty sharp points on them so I don't want to cause any issues that we are going to end up at the vet for.
That's why you stick with the softer, non-weight bearing bones like necks, backs, wings and knuckles. They can chew them up without them splintering for the most part, though I'm sure accidents do happen. But accidents also happen with kibble too.

I think it's generally pretty self limiting, i.e. if the bone is too large/hard, then they won't be able to consume it. If they've stripped the meat off and don't seem to be making progress on the bone, just take it away. I usually trade for something my dog goes batty over like a bit of green tripe.
