Just two points from my observations.
From the overhead pics provided, this '+' intersection has clearance bar lights (3 yellow in pavement hold lights). Accepting that these are normally used for low vis operations, it might be a good idea to use these for A380 movements, ie hold the A380 at intersections until the preceding aircraft has reported, in this case 'on stand' or in another case 'at it's next cleared postion'.
The apron area boundary is marked in this case by a road, on other airports there is often a dark pink or red line which I assume marks the boundary between the declared taxiway width and apron area. The 'see and avoid' principle surely still applies on the ground, if it's hanging out past the line or boundary, stop and get it investigated.
Just my opinion.
