For an already established coach, those regulations dont really matter though. It's as you say, being "banned" only means you cant basically be an representative of said country or get any of their benefits. Hell, look at how many top athletes have flocked to Sutton after all of this. We have pro's on this thread already saying they've pretty much ok'd/accepted/forgiven what has happened to Sutton's past, because they could gain athletic achievement under him. ETA: And I'm not saying that's wrong, it's pretty much a personal decision that each has to face.

I dont think any country makes coaches be certified, whether working with kids or not. I know of several coaches in my area (Raleigh) that work with and hold kid triathlon camps/races that arent certified with anyone (nor will they ever be).
