iPhone 15 Pro/Max more fragile than previous iPhones

Have you seen or read about the 15 Pro/Max being more fragile? Some commenters suggest that the more rigid titanium chassis makes the glass more susceptible to cracking.

I've never bought AC+ or any sort of insurance for my phones, only a case, but I'm getting uncomfortable..

Are any of you case users actually worried? I'd estimate that I drop my phone a handful of times each year onto bedroom carpet or bathroom tile, usually from waist height.
