well, then ... map them! No, to be honest. The map will never be "finished" so something will always be missing. In this case, we don't need a note, especially not from mappers. Usually notes are for errors. Additionally, bicycle and pedestrian ways don't need to be mapped separately. It is very common that you just tag the street and don't draw additional lines. I would close this here as it is no "error". Just map them if you have free time.
