Founds vulnerabilities faster? Rewritten it in a safer language? Made a safer doas-like subset compilation target? Made it harder to trick a single person by having more eyes on code reviews?

The only valid point is your last one. It's not only about having more eyes either, but also backup eyes for when the main eyes are unavailable.

All the other things you mentioned are just things you personally wish for but may very well be undesirable to the project.
