I don't see how it can damage the wheel. But a skewer that's bent reflects likley having been
installed not-quite-tight-enough or perhaps askew (maybe on top of a Saf-Tee lip??).
Add a drop of oil on the cam and the threads and ensure you're locking it just as you would any
other skewer - hard enough to see the print of the lever on your palm for a few seconds ( but less
than a purple mark!).
The wheel's surely OK but I would look at the fork tips if the skewer slipped in use. Are they
parallel? That is a concern, but still much less serious than a loose skewer out of the saddle
in traffic!
