These things can add value, but no one needs a new hire to point that fact out. I'm also skeptical that a freshly hired IC's values will align with business values, even though the latter is what shapes the tech debt and tooling you're referring to.

The point being is that new hires will bring fresh eyes to an organization, whereas the team in place might be numb to some of the issues.

You don't need a new hire to fix those problems, but it certainly helps shed new light on some problems. Especially if you are hired as a senior dev or a team lead, you will be expected to fix some of those things.
