Yes there certainly can be impacts.
My most recent MAD flight was cancelled and the flight I did take probably took 30-40 minutes extra flying time.
It's not predictable and so it might well be worthwhile giving yourself enough leeway to cope with a cancellation and extra flying time. If this means an overnight to be sure, then I would recommend doing this. The situation in France shows no signs of an early resolution.
