Any thoughts on doing it no matter what? I don't really see any good reason users would want to override it.

Sometimes you want to set inspect on a subprocess when your main process is just a small wrapper. We could also tell people to move towards https://nodejs.org/api/inspector.html instead for this functionality.

I'm okay either way, just remember that changing this would be a breaking change.

Yes, it looks to me that could be the case, and this change would then be a breaking change if any users is doing this. Based on this, I personally think only doing this as a default value (what the PR currently does) might be better?
