Officers are employees too. At what level do you make distinction?
I'm not sure that's always or even often true, despite the 'O' in the name. You're generally mostly talking about the CEO plus directors.
I mean, nothing stops you from making it into job requirements in your company, but, apparently, this is not a requirement at Tesla...
What, nothing stops you making director-style fiduciary responsibility a job requirement for normal employees in your company? I'd, er, check with a lawyer before you try that one.
