I used poly-covered dual duty on some of my quilts that are our "couch quilts" that are in use "all" the time.
They are over 15 years old and have held up "fine"
I did stitch in the ditch quilting - the thread did not cut the fabric and it hasn't come out.
And in 100 years - so what?
It might depend on if you are making an heirloom quilt to just look at - or one for the kids that one expects to get used.
