Hornwort (Ceratophyllum) doesn't produce roots, although it seems well
anchored where it grows naturally.  I don't think it would be good food for
Flags.  If they eat it, they probably be able and willing to eat a lot of
other aquatic plants that you might not want eaten.  Hornwort should be
bothered a lot less than rooted aquatic plants by being pulled up and
replanted.  I should think that Vallisneria would be set back by being
pulled up and replanted.  Why not cut back or relocate the hornwort?
