Are we getting rid of the "implicit/explicit" distinction in docs? I think we should and only present the concept of "required/optional" to users (no references to depends_on).

Yes :) In viamrobotics/docs#4309 I moved the already-deprecated reference to explicit dependencies out of the module dependencies page and into the changelog. Big fan of removing that terminology from users' eyeballs, since it was confusing to begin with!
