Well that's the thing; most of these rules are left general and open to interpretation. We couldn't write a rule list to fit each specific scenario, because situations change all the time.
That's why, IMO, the wording could be something like "no breaking the cade unless valid circumstances arise." - is IS still broad written like this, BUT it acknowledges that there are circumstances where cade breaking may be necessary without having to list every circumstance, thus making debates about cade breaking less that it occurs at all, and more about the WHY - whether it is out of trolling or mingeing, or out of necessity.
I know I'm overly analytical sometimes. It's an old habit that I got during the not-too-long-ago days of writing role playing games in college for fun... somehow, I'd always end up writing a mechanic or rule that was worded as such where SOMEBODY could figure out a way to break, or exploit it. Since then, whatever bits I have time to do in my spare time are less ... break-able, for a lack of better words.
