I can’t speak to who has access to the bug tracker, but I can say that default airports are also done by a team from Orbx. (Note that this addendum to the World Update 2 release notes mentions Orbx.)
Airport fixes are often deployed in world updates. As you mentioned, many of them are a consequence of new data inside the boundaries of the world update. However, airport fixes outside of the world update area are also deployed in world updates, such as this update from World Update 8.
I don’t know why BWI was not fixed in this round. I don’t have visibility into what dependencies there are, etc. But I can assure @PopsMcDaddyo that it is in the bug tracker. So it will be fixed at some point, but unfortunately, I don’t know when.
