Seems another user omission. In general, `junction=yes` can be used for named junctions, and the confusingly UK-named `=motorway_junction` for exits. However in this case, HK has the special practice of gazetting some roadways to be named "Interchange" as "streets", and it's not straightforward to determine the extent of YMT Interchange when it overlaps with Jordan Rd.  For consistency and better support, they can still be considered.
