This is strictly a convenience feature request.
I think the next logical step for Channels now that it has started beta steps in to streamlinks live tv in the guide is to have a Source for Live Streaming Services that will populate automatically with the streamlinks for live TV services that the end user states they subscribe to.
This again is strictly a convenience request like the "bonus" Channels that people receive when they subscribe to any TVE source. Of course with the new beta feature, these can be added manually via custom channels (the same can be said for those bonus TVE channels). It is just something to think about while the developers iron out kinks in what they are currently developing. In many ways streamlinks are a slightly more advanced user feature and this type of source may be less daunting for more casual ChannelsDVR users.
