there are some groups that don't like to play with Rule 0
Isn't playing without rule 0 the same as playing with it?
RULE 0: "Feel free to ignore any rule if you and your players feel that will improve your game."
GROUP: "OK, we choose to use all the rules."
Yes, rule 0 is important. However, taken too far, it can also result in some of the most tyrannically stupid, group breaking moments that you'll ever encounter in D&D, and that should certainly be acknowledged as well.
You don't need rule 0 for that to be possible.
