I couldn't rotate back soon enough, my bad; though arguably Airport T2 has higher priority and importance than Hung Hom. I did intend to work on this, so I will pick this back up.

Still, while the changeset is indeed lgtm, we still can't close this note yet because as I later discover while splitting the ways, this has two parts: the west side (by earlier changeset of @kingkingHK ) and the east side (todo).

Ideally the east side should not take too long.
