The ramification is that not all Prohibited Devices are automatically prohibited because they are listed under the Prohibited Device umbrella. Nor are all Prohibited Devices equal.
It is not being listed as a Prohibited
Device that makes something prohibited. Prohibited Device is just a category (not even really a definition) with no legal restrictions attached to it on its own. It derives its "prohibitedness" from being included in various offences in the Criminal Code. For example, it is illegal to possess Prohibited Device without proper authorization only because Prohibited Device shows up in the appropriate Possession Offence subsection.
If a certain type of Prohibited Device is explicitly excluded from various offences that otherwise include Prohibited Device as a whole, then that explicitly excluded type of device does not share in the same prohibitedness in under that situation.
