There are a few references to 2016. There is also a target/iphone8 folder. Don't see any reference to iPhone X though.

"iphone8" might not be a reference to a product name but the internal model numbers "iPhone8,1"/"iPhone8,2" which are the 6s and 6s Plus (released in 2015). The iPhone 8 model number is "iPhone10,1"

edit: there appears to be a reference to "N66" in init.c, which is the codename for the 6s

The iPhone 6S, which was released 2015 with iOS9, had the hardware string 8,1, so nothing unexpected there.
