This is a bad attitude, imo. The Go standard library wouldn't be possible without generics [1]. It's just that the functionality exposed to the standard library isn't exposed otherwise.
If it's a feature needed for the standard library, then it's safe to say the devs will need it to. The devs aren't (shouldn't) be consistently writing programs that are more trivial than the standard library.
