My comments have come from professional band members, Orchestra players and solo players, (I am a home player) and I always take note of what professional say, so I think you may have misunderstood my post.
If you are a OMB or are just singers guitar players etc, then backing tracks (Of any file type) are fine, as it can give body to the performance.
If however you are in a group where you already have the live backing, then forget sequencing, as it will stand out like a sore thumb. (If you don’t have a drummer then Drum backing is fine)
Here in the UK people Do notice.
Hope this makes it clearer
