You also raise another interesting point - the norm is for 5' widths, which I assume has as much to do with ease of handling as it does for manufacturer's capacity.

glazing can be replaced, but it's a non-trivial excercise - and has to be done from the outside of the building. usually it's done from the window washing platform.
the 5' module has more to do with the standard office planning modules in the united states than anything else. in metric countries it's often 1.5M. in both cases the smallest office is two modules. for residential buildings you'll see more variation in the unit size, but they almost never go past 7' because glass is hard to come by with both dimensions greater than 7' due to limitations in the tempering, laminating, heat-strengthening, or low-e coating machines. they have an ±7' width that the glass rolls through. since the vertical dimensions of the main lite of glass will almost always be more than 7', that generally dictates a < 7' width.
