Is it where the cameras are? Then yeah probably necessary if not then might could just be filled depending how bad/likely to spread it is.
Each state has specific laws on repairs for state inspection, usually in non critical areas it is 1.5" . Your service center may not do repairs period on glass, I'd check with Safelite but it is probably too close to the edge, there is tons of pressure the closer you get to the glass edge so it may be liability thing. If they start drilling it to prep for the resin and the whole windshield breaks, the customer is going to expect a full glass replacement since it was "fine" before you touched it.
Don't they hit you up with a claim strike though? It's not free if you have to add a claim to your record.
Would cost you practically nothing to try one of the FIY kits; I've repaired several chips that way and never had an issue.
