Hobbs 80/20 is needlepunched and spray bonded; it does not contain a scrim:

I agree that the binding (and even the fabric in the top) will develop issues before the batting does -- as long as you quilt it within the batting parameters. In the case of Hobbs 80/20, quilting lines need to be 4" apart or closer.
