This is not the case if you get an official rules upgrade. If you refuse to use the new rules it is on you, not the designers. They just don't tell you, that you have to switch.
Edited out an insulting statement.
I think Oberoni gets always thrown around when someone wants game designers to make decisions for them, that they should make themself.
I hope that is not insulting.
From now on this shall be the Embarash fallacy:
Thinking you have to use the inferior variant of a rule if not explicitely ordered to use the better one just to reference Oberoni whenever someone suggests to use the better official variant.
Closely related to the fallacy to think, a game can be created that is perfectly usable for all (edge)cases and all preferences.
