Didn't dig too much in the code of the current smooth plugin, but I would guess that it splits a stroke into several splines if there are angles that aren't smoothed, smoothes these individually, and then splice them back, throwing away the "external" handle so if there is at least one unprocessed angle in the stroke, everything is fine...
To get a smooth "closure" also the first derivatives have to be equal.
I haven't looked at the code at all but what you suggest seems reasonable.
