What you just said is true.

One genre I am prolific in is Latin jazz, and that is because I am proficient at classical and Latin guitar (among other styles) and can use BIAB real tracks for bass an percussion etc.

As long as you use backing tracks for, well, a part of a backing band, you are good, but I think you have to be able to play something to give it that real human touch. For this, BIAB is a wonderful tool. If you just grab a style, push render, and try sell that as yourself you won't get very far.
