It’s a balance. Sometimes it is worth spending a ton of time leveling up your team (teaching them to fish), and sometimes it’s much more helpful to have you do the work yourself (we ran out of food and you’re our best fisherman).
I get why people say this but let's be real. You optimize for the review cycle. If I'm told not to help as much I'm dropping it down until I'm told to help more. Then I'll correct the minimal amount necessary.
