The characterisation was against Go 1.15 as that is what is current in the version of Debian we're using (11?). So other than noting that Go 1.18 adds Generics but they can be ignored due to us targeting 1.15, they weren't mentioned. As I recall the another thing we get in 1.18 (as a side effect of the Generics constraints mechanism) is a slight improvement in static checking for certain constructions of type switch.
