If all I had to do was load the frame and hit a button I would get bored quickly. That's the point when the machine no longer serves you. You serve the machine. I suppose the next big deal will be the addition of a few lasers and motors so the frame can map the center and borders then start quilting. All you would need to do then is set the unfinished quilt on the rack and press go.
Back to heavily quilted quilts. They're nothing new. I bought some "Quilter's Newsletter" magazines from the 80s and 90s at the thrift store today and there were enough examples in them of heavily quilted quilts (including a couple quilts dating back to the 30s) to indicate heavy quilting was not uncommon even in older quilts. The only thing that has changed is the style and technology. There were a lot more crosshatched and straight line designs on the older quilts. Longarm machines have made stippling, meanders, feathers and other flowing designs much easier to achieve. Some quilt battings also require what I think of as close quilting-lines every inch or so. I think older battings required closer quilting because they weren't made to stay together like most modern battings are.
