My front wheel on my disc brake road bike would move around slightly during heavy braking. The skewers were both external cam and titanium (Salsa). I don't know for sure which was at fault, but replacing with internal cam steel skewers solved the problem. I had initially attributed this to the properties of the external cam, but someone pointed out to me it could be a bit of stretch in the titanium, and that steel was superior in this regard.
Also, some skewers come with aluminum non-lever-side nuts. Those threads sometimes aren't strong enough.
My main point was that if the wheel can move with respect to the dropouts, the skewer could potentially bend (even in the absence of more profound damage).
