The problem with reminding people of the loose ends is that scientists are already keenly aware of them, and idiots grab on to it to attempt to validate their own crackpot theories, and to claim "revealed" knowledge and faith are as valid a way of approaching reality as science is.
Fact remains that science is the best approximation to reality we have, and that the scientific method is the only legitimate way to acquire more knowledge. I think that's more important to stress than the (self-evident) fact that we don't have absolute knowledge.
