I would say recommendations 1, 2 and 3 in the brief.
The purpose is to limit the type of information that can be obtained. I think that's what the government is trying to do, so specifying the information in question will reassure those who are concerned.
The idea is also to limit the types of persons and entities subject to these orders. As it stands, the production order applies to any person who provides services to the public. That's a broad range of people, so it would be possible to obtain people's medical information, for instance.
I think it should be limited to telecommunications service providers, as in the earlier provisions relating to non-warrant requests. I think that would restrict access to only the information the bill is really trying to capture.
