From @negz comment in: #754 (comment), copied here for convenience:

Huh, I actually forgot we had these pointer helpers in runtime.

We usually use https://pkg.go.dev/k8s.io/utils/ptr instead these days. I'd suggest that. We should probably deprecate the ones we have in runtime, but that can happen in a separate PR.
