I see no reason for chrome bores unless the barrel maker charges less for them. As far as no tox requirements, guys who shoot five figure guns don't shoot steel, they shoot no tox that is perfectly compatible with old guns and soft barrels. If monobloc is chosen, I'm sure that it will be fairly seamless and will not require an ugly engraved seam. Ken's idea of a U.S. manufactured monobloc with final barrel and rib construction somewhere else seems to be a very novel and workable idea. That would take the worry about lug and doll's head fit out of the "import" equation. That is some of what sunk the ICD ship.
