It's really important. This bill actually does a great job of being specific. It's very clear that the exemption applies to three sorts of behaviours, which are diagnosing, maintenance and repair, as you said.
I would also say that it helps us distinguish between the kinds of activities that we want to promote here—repair—which extend the longevity and useful life of goods, keep them out of landfills and support local economies in terms of having third party repair technicians have ample work.
However, it doesn't include things like environmental controls and emissions. It doesn't include things like parts of the system that might affect cybersecurity. It doesn't include things that might affect consumer safety or modification.
I think that the clarity of language is essential. It's very clear here that the types of activities that are being permitted are really related to repair.
