Here I think we just have a different subjective perception of what simplicity is. I much prefer have two orthogonal systems which do their own business than having a single more powerful tool than do both (like having slices + references instead of the all powerful pointer)
Anecdotal note: more than 10 years ago, the Go team pitched why they didn't need generics nor macros, because code generation would solve both problems (+ others), and now they're on their way back to add generics to Go (with a lot of hassle).
