Not sure I agree with that, but you could be right.

This is one reason that I use a lot of submix buses. That way I get
meters on portions of the audio.

But think of it this way: If 0db on a channel meter represents 100% of
what the system can do then:

1) Is there any value at all to going higher?

2) I can raise volumes on individual tracks so that they meter above
0db. Am I distorting that audio, or am I just going above some
predefined level?

3) If I'm not distorting that specific audio then how high can it go
before I do?

   The answer to #3 is what is typically referred to as overhead. How
much overhead do we have in Ardour?
