This is my top desired feature for skaffold. I hope the maintainers can take a look at this soon.

I am not sure why this PR doesn't get any attention from the maintainers, but I rebased it to resolve the conflicts with main. In my workflow, and I think I am not alone, I need a breakpoint as soon as the first line in main() so such a feature is crucial.
