This is great, and also good to encourage with people who are more junior. They might think they’ve explained the thing from their understanding but it’s trivial to omit details in that position too.

I’m by no means junior but I’m new on a team, and I’ve had to remember over and over that the giant blob of the state of everything is unfamiliar to me, familiar to my team, and when I elide details I’m not saving anyone any time because I’m not sure whether those details are relevant or even if they might reveal where I’m off track.
