It might not be intentional, but it certainly might be.
On a different vehicle some time ago, I went to an auto glass shop for a chip repair. When I dropped it off the guy conveniently told me (covering his behind pre-emptively), "oh there's a small chance that the repair might cause it to spread and crack". How small of a chance I asked. "Oh like less than 1/100, I'm sure you;ll be fine". So I ok'd the repair and said I'll wait over in the coffee shop next door.
Not 20 minutes later I see the guy walking into the coffee shop. Oh here it goes I thought to myself. Yup mine was one of the "rare" ones that he cracked. Oh but he already checked and he can get one in today if I agree and he orders it in the next 15 minutes. I went and looked at it, and it was a couple inches from either side of the chip, but not in the line of vision.
He said he'd even eat the deductible so zero out of pocket for me. I sensed a total racket. All seemed too convenient. Pulls you in on a special chip repair price, "accidentally" causes a crack then pushes replacement where he makes his money.
In the end I said I'll think about it, left and decided even if it needs to get done I'll never touch that shop again. Held off, and a few years later it has never spread further even in -20C winter conditions.
