But if you use maps, slices, append, make, you are already using generics.

Sometimes having another built-in function would be helpful, and generics
would provide a way to write those without changing the compiler. What I’ve
seen is that built-in functions and new types expanding on the map/slice
pattern will not make it into Go 2 without a major reason.
The other call for generics is interface{}. The Go 1 uses of interface{}
can make strange code that maybe would be more comprehensible another way.
