There are two important differences:
1) The meaning of a particular way or node is separate from the value
of is_in. On the other hand, the meaning of a requirement to stop is
NOT separate from knowledge of the junction to which it applies.

2) ANY kind of way/node could be marked with is_in. On the other hand,
marking the junction to which a requirement to stop applies is only
relevant to that particular requirement to stop.
