I don't think RJack was implying you wouldn't have procedures to deal with all these problems, just that your procedures might be different than his, thus prompting a longer amount of time discussing things on the surface.
I went cave diving with a guy who had been full cave / trimix certified by JJ before GUE existed and hadn't been doing cave diving in years. We went out and did two OW dives to practice skills and iron out differences in procedure before we even went down to MX to the caves. Then we still were finding out little differences as the week went along after >20 cave dives (e.g. little differences in reel handling protocols and having buddies applying tension on the line) and that was with a buddy who just needed to be caught up to date and had a strong motivation to adopt the newer protocols just to get on the same page in order to dive with other GUE divers. And that was just all within cave1 limits. After we left we handed him off to some other cave2 divers and they probably got him caught up on jumps, stage bottles, etc.
At that level there's a lot more going on that just agreeing on hand signals, OOA donation and gas management like you do on recreational dives.
