Channels are not linked by default. So your probably referring to what happens when you add a thing via PaperUI. PaperUI links all channels unless there marked advanced in the thing xml. You can use advanced to not link the channels automatically, but that might not be for what advanced is intended for. It’s for specifying if a channel is functionality not used in the most common use cases for a thing, but for additional functionality. It might be this overlaps with what you want to achieve. But that’s up to you.
That is definitely my recommendation. The Item names end up being long and meaningless and as soon as you need to do anything at all beyond the default, which happens pretty quickly even for the newest and least technical of users, they have to switch auto linking back off.
It’s really more trouble than it’s worth IMHO and I for one would not be unhappy to see that feature dropped.
