From time to time, the CRTC updates certain policy frameworks. For example, they do make changes to their community broadcasting framework, so you could see them change the categories of licensees in that context. The CRTC is currently engaged in the process of updating its indigenous broadcasting policy, and so you could see, for example, changes to terminology. You could see changes to the way that those stations are classified. The amendment as drafted is just very static and based on how those things are defined currently.
Again, I don't want to speak to the mover's intention, but I think it's to recognize that those things may shift.
