Yes and no. In OSM ways are represented by lines, although they have a width. While you can step from the footway easily to the tram platform, routers need a way to connect both. 
If such is asked in Streetcomplete, best ignore it and walk on. The app cannot judge, whether the question is meaningful for the particular way, so the mapper must decide. Creating a note also won't help, because somebody has to close the note, as the question is not applicable in the specific case.

Happy mapping,
