I did read your blog on the subject, and found it to be, at heart, a disagreement with the evidence-base for a single recommendation from a document hundreds of pages long Not exactly a fair critique in my opinion
Sure. This is the practical application of a theoretical construct. You can decide that a certain grade of evidence is not sufficient - against the NHMRC recommendations - but applying it inconsistently makes no sense. You should apply it to all areas of evidence

The level of evidence for tobacco-related harms is never above Grade C (perhaps Grade B in some very specific cases), because you cannot run an RCT on cigarette smoking. Similarly with mesothelioma and seatbelts
-
So if you reject all Grade C evidence, which is, I would argue, a methodologically unsound method of evidence appraisal, you should similarly be demanding furiously the RCT evidence that cigarettes cause harm and that asbestos is bad
