Of course, since that was the first one with a landing, it would set the precedent for subsequent one.
It might be worth nothing that on the Gemini missions (as well as Alexei Leonov's Voskhod mission), the commander remained inside while the pilot performed the EVA. On the lunar surface, of course, is a different story, however, as the spacecraft is essentially "in port".
