This is not at all about a complaint or bug, just a question.

When i drag and drop individual real drum and realtracks from BIAB to Sonar, the resulting audio clips are in stereo.

As each track is just an individual instrument, does it really make an audible difference, for each instrument to be in stereo, in and of itself?

In Sonar it is very easy for me to right-click on each clip, and select "convert to mono". I am tempted to do that, use less bandwidth, etc.

Of course I will pan each instrument to different places, and the final mix will be in stereo. I am just wondering what the point is, of each individual instrument to be in stereo by itself? Can people hear a difference?

Or perhaps, if one leaves the clips in stereo, should one then not pan the clips in Sonar, but leave them all at center? Are they already panned as a combo, in the way that they were recorded?
