Depending on the type of rock chip, just repairing it is fine. Happened with my Model S on the terrible roads around here (don't even get me started on the chips to the paint...)
Mine was a small bullseye style chip in the direct line of sight of the passenger. I had a service come out and fill it. They have all of these warnings and disclaimers to help set expectations.
The repair will not be 100% back to normal. The epoxy just isn't the same as what it is patching. That said, the repaired chip has less chance of becoming a larger problem and unless I point out where it is, most folks don't even notice it.
The guy that repaired mine was super friendly and very good. He even noticed a second bullseye chip down low on the windshield (towards the defrosters) and filled it for free! (I made sure to compensate with a nice tip)
Pretty much, as long as the chip isn't spidering out into bigger crack lines, a repair is fine.
