Ok, I've now read the link and also understand your description. My gut feel is that it is insignificant an effect, and even if it was there, how critical would you have to be to notice it? I'd also question if it was necessarily negative, but this might depend on the exact composition of the out of focus areas.
It is late here now, but I can grab my 100-400L tomorrow and try some relatively longer exposure shots hand held with IS, vs. fast exposures without. See if I can really notice this. I've lent out my teleconverters so can't try longer for now.
