Using 'Add Track' for an audio track does not have 'No bus' available as audio input

I refer you to the earlier messages in this thread.

But there are no real disruptive effects mentioned… does it affect something important?

What is disruptive or important is highly subjective. If you don’t consider the side effects mentioned as such, good for you.

For one, record and monitor is disabled on a track with ‘No Bus’ selected (workaround doesn’t accomplish this btw) which is significant if for example, a user wants to use ‘Record All Enable’ or ‘Monitor All’ commands.
