This is very interesting, and may be another example of a manufacturer offering what was available to them at the time of production. Perhaps it was a more cost effective deal from a supplier, or a purchase of unused stock. This conversation has come up before with other brands.
Don't most people find that braided hoses offered with GE's tended to last longer then some other brands? I've got a couple of hoses that went with GE's and found the hoses to still be air-tight and flexible even today - when say, an Electrolux (for example) hose gave up the ghost years ago.
