I guess I imagine that as in my country the pharmas managed to get a special extension to patent terms just for themselves and no other industry that they have enough sway with government to push it so they at least only publish proven side-effects.

Why would gov make this a requirement, that's part of my question?

This sounds like if someone gets run over wearing support stockings the support stockings have a document with them saying "may cause you to be hit by a car". This is strictly true but not helpful and the causal connection is decidedly tenuous.
