It sounds like you are not going to be doing the quilting. Call the quilter to find out what their requirements are and if they would accept the backing with the temporary strips. When you drop the quilt off be sure that you tell the quilter that the strips are not part of the backing. Backings are often pieced and the quilter may think it's just part of the backing and quilt it in. You might get an unexpected accent strip in your backing!
