Is LHR maintenance area gonna open in future?

A large area can be seen on the east side of the LHR map. In reality, this is the maintenance area for British Airways and Virgin Atlantic, but it is currently inaccessible in the game. I would like to ask if there is a possibility that this area will be opened in the future.

PS: Although it is not yet open, it seems that some of the building details in this area have been subtly adjusted in past version updates (for example, the hangar doors have been opened). Has anyone else noticed these small updates?
