Feline Fanatic,
The key to excellence in whatever you do, however you do it, is to care about the end result.
The LAQ spoken of in the original post doesn't understand that she has to CARE about the customer perception of the end result. She doesn't get it, and may never get it. But that has nothing to do with using a computerized system.
Bottom line is that if someone trusts you to LAQ a quilt they made, you must ALWAYS discuss any kind of change that is needed before making the change. That has nothing to do with the LAQs skills at quilting or the use of a robotic quilting system. It's simply good manners. And, if you're in the business of quilting for $$$, it's also good business.
In case you're wondering, yes, I use a robotic quilting system exclusively, and, no, I have never machine quilted without it. No, I do not quilt for $$$, but I do quilts for others and have had to ask a few folks if I could change something, but always with good reason. I would never presume to make a change without the quilt makers permission. Again, that is simply good manners.
