Around here, they stopped putting sliding glass doors in houses, probably 25 years ago. I’m sure you could probably request one, in a custom build, but I never see builders installing those. There are more secure options available.
I rented an apartment, with a sliding glass door, about 30 years ago. Even then, there was some sort of a long, steel, locking bar, on the door and another device, that was a lock of sorts, with a pin , that went through both doors. These were in addition to the lock that was installed on the sliding door, when it was manufactured.
I never was just real comfortable with that sliding glass door, even with three locking devices on it. What I see today is more of a traditional style door, with double pane glass, in the center of the door, leading to patios and balconies. That’s not the most secure option, but I certainly think it’s better than a sliding glass door.
I don’t know how old the house in Idaho is. I’m going to speculate that it’s probably an older home, that was remodeled, at sone point and the sliding glass door was left in place. Again, that’s just my opinion.
