Master Black Belt
As I said, it lacks the "on your back" stuff, but the suwari waza gives a framework for learning to fight from other ground positions. The same basic principles that can be adapted from standing technique can be adapted from suwari waza, as well. It's unlikely to look like the training drills from suwari waza, but it's there.
All the standing techs can be done from suwari ...it the ease of movement that I'm getting at yes they can be adapted like any other as you say just that is one thing I must admit does not instill me with confidence lol
