HaLeiVi, I am addressing one specific point:
A problem with this viewpoint is that there are minimal sources for downgrading a pastry manufactured from a viscous dough based on its appearance.
I don’t know why one would be mechalek between something which once had the appearance of bread, and something which never did, and since we all know the sources for something losing its toar lechem, there’s no good reason to think that there can’t be something, even blilah avah, which never had it.
Of course, one could argue that wraps do have it, and I don’t really have a strong opinion on that.
That which he writes, “While the precise definition of this term is very elusive, it seems that it is a prerequisite to be considered a bread product”, as well as, “to say that a wrap has crossed the invisible line that divides them is a judgment call”, are, IMO, on the mark.
