I understand. It just seems that if you are in the design phase and if there is not a significance to the asymmetry as a design element, that you would open up your options for having it woven if it were symmetrical. but if you plan only a limited weaving, then you'd likely end up at a place like D.C. Dalgleish, who weaves great cloth on single-width looms (so I understand from Barb T, who should know).
