Nobody really cares about speed of shipping. People generally either need things fast or in high volume: if fast, you might as well fly it over; if in high volume, you might as well use a ship. You can design your supply chain around the shipping time with basically no cost: that’s the principle behind JIT.
People care about volume and price, things which this corridor don’t really affect. This corridor isn’t going to be cheaper than transiting through the Suez, and because of that reason (if nothing else) it’s DOA.
