Thank you for the question.
As legislative clerks, we do not do the linguistic revision of the text of the bill. We only review the amendments. At the reprinting stage, the jurilinguist team is involved, but the interventions are limited. So I couldn't tell you whether this kind of amendment is necessary or not.
The legislative clerks can renumber, but I am not convinced that they can add references because they are subject to Standing Order 156. I know that corrections are made, but I don't know the details.
