gaon: The SHA”T states that in the name of the Pri Chadash. The initial Shita is quoted from the Divrei Yosef. The OP seems to think that using Matza Smura Mishas Ketzira is something “new” when obviously it is not.
One does not have a chiyuv to eat matza except on thef irst night; after that if he wants to eat “bread” it has to be non-chametz. What I don’t understand is why it bothers the OP if I want to eat from matza that is Shmura Mishas Ketzira? I don’t know anyone forcing someone else to eat from this type of matza.
