I agree. Pro-active audits will only go so far, there is definitely a need for other measures (which are implemented as well). A Content-Security-Policy is as far as I know still really hard to implement well (as in truly protecting assets instead of being a policy tick-off) on WordPress with external plugins and themes. Sadly, a CSP will not protect against attacks running on a post npm install in your development environment, as this is also a risk of using npm packages.
