I think that VANOS caps playing role of dusters and "paper" for part number - nothing more.
There's central screw which is holding spring in it's place and because of rectangle profile this spring will not bend easily in the direction to come off and there's no such force applied to it. So if it want to come off - it will, and cap will not save it or hold in place.
Any bad experience with running VANOS without caps?
