I think systems programming, like system tools or cli tool for example can also be done with a garbage collector e.g. in Go or Ocaml. For low-level development you would usually expect that the program manages memory itself, not some garbage collector. This is not black and white, some approaches of reference counting for example might be suitable for some low-level development. Or in some languages you can choose like Nim, D or if I understand correctly, now in Swift ?
