There seems to be a tacit acknowledgement that the shavings are unlikely to be full width.So why would you drag the extra weight around?If you don't need a wide shaving,its easier to use a narrower plane and less tiring.Camber on a jack plane is the accepted practice,less so on a smoother.For solely bench work,a 5 1/2 may make sense.For an only plane I would take a No 4 any time.
The shavings width on a smoother will be as wide as you get them on whatever plane you have, consistent with achieving a feathered edge to minimise any planing tracks on the workpiece.
With a shaving thickness of only 1-1.5 thou there's not much effort involved in pushing a smoother. Consequently I've always found the extra width of a 4 1/2 or 5 1/2 to be an advantage on a smoother as it results in fewer strokes being needed to cover the workpiece and fewer planing tracks. However, we're all responsible for our own furniture making, so if a 04 smoother suits you and your work then that's pretty much the end of the matter!
