There probably is some truth to the notion that dustbin fairings increase sensitivity to x-winds such that instability could become an issue.
That said, we have the Vetter streamliner, the Ecomobile, and that streamliner on the EM home page, and as far as I know all of them are streetable and are claimed to be stable.
Perhaps the problems with the old dustbin fairings were:
1) they didn't have enough tail so that put the center of pressure ahead of the center of gravity, and that causes instability just like firing an arrow backwards; and
2) they were racing and so the speeds and conditions they were operating in were less forgiving than the street.
