If you accidentally trip over your cable, the cable will break but the port will be fine.

Tbh this is thing I'm not excited about the USB-C future on. On paper, I would expect that Lightning be more problematic since the springy bits are on device rather than the connector. In practice, I've never seen a Lightning port fail since it's come out. Micro-USB, which is much closer to USB-C in design (obviously with improvement) for me has basically come with an expiration date. I don't have enough USB-C stuff yet to say if that's going to continue, but it's a concern for sure.
