Screen design are all about tradeoffs, but some people got it right years ago.
The 5X in particular also made a bunch of other decisions that helped the glass survive, like having the frame raised slightly past the glass, so that the frame would absorb the impact rather than the glass itself.
That still means if there is a hidden fault in the phone or they brick it by sending an update, they are still responsible in my understanding. But no longer if I give the device to family member and he/she is careless enough to sit on it.
When you buy shiny sleek phone with edge-to-edge screen you should understand this is not a phone to be dropped or sat on. It is not possible to fit so much screen, electronics and battery into such sleek enclosure and make it drop resistant. If you need drop resistant phone, there are phones that advertise the feature (see: https://www.techradar.com/best/best-rugged-smartphones)
In other words, dropping an iPhone is not an intended use of the phone.
