Agreed. We try to stick to (if #25 chain) at least a 22t sprocket on the drive. Some rough tests I've done have shown this to be the smallest tolerable size. And when I say tolerable I mean it works pretty darn well.
However, if you're aligned perfectly the smallest of sprockets won't give you an issue. But are you really going to be perfect?
