To me this should be approached as a security issue. Any time a crew member has to open the cockpit door, it creates a security vulnerability, which can be exploited if planned for.
At my last airline, the crewrest was positioned behind the bullet proof cockpit door to keep cockpit door openings to an absolute minimum.
Out of site out of mind. The flight crew were never visible unless absolutely necessary.
If the media were to discover the increased risk to security with the EK crew rest configuration, I think there could be a rethink on EK's part.
Not knowing if there is an EK pilots group, these types of organisations are what bring issues like this to managemants attention.
