Slightly disagree.

Needing the managers permission is more of a "wartime" mode.

For peacetime the management should set a culture of peer review and data and logic driven discussion. The culture would ideally have a Rust lover sit there and think "would love to do this in Rust but...." because they know their peers will be affected by this decision.

The problem with management approval required is it usually meams no or bias towards management pressures. A management veto that is occasionally used may be better.

Disclosure: not a Rust programmer but pretty neutral on it. It is on my radar if I get a problem Node or Go can't solve.
