I hope not, but even then a thin plastic frame isn't the worst. One could 3d print it for example. The worst I can think of is using a thermoset glue (or a thermally stable epoxy) on metal only parts. Then no one could fix it without replacing the chassis.
However, the trend these days seems to be glass backs and this necessitates rubber/silicone like glues to make the glass less likely to break when metal deforms on impact. I don't think there are any glues that are rubber like flexible and they resist heat. So at least until there are glass backs we're fine :-)
