10 years ago I didn't think about directions on paths until I climed Mt Fuji. There are 4 or 5 operlapping trails, access roads, bulldozer tracks - all overlapping where they meet to share certian services (alpine huts, etc), and all the trails are very well marked Ascent or Descent - but the oneway tags are not rendered, so current renderings rely on the labels to mark them descent or ascent. Having an arrow similar to iD's rendering of the directional triangle would be about right.
And then there's the problem of no color renderings for ways.... (red outline, etc) - vitally important when all trail signs and maps (for fuji and other places like subways and complicated tollway intersections) are color coded - but I can't convey that vital info through OSM-carto renderings (AFAIK). But that's for another thread.
584 Render oneway arrows for footways and stairs
912 Oneway arrows not rendered for cycleways
In addition, oneway arrows are not rendered on tracks - see: http://www.openstreetmap.org/#map=17/55.42008/10.39141
Here we have allotments with an (elongated) circular highway=track with the tag oneway=yes because only clockwise traffic is allowed - but the map does not show this.
On footways, stairs, paths and tracks, black arrows would perhaps look slightly less 'clean' than arrows on normal roads - but in my opinion, this lack of direction arrows on some ways is worse. It is a lack of map-function that should not be permanent - a solution is needed. If arrows are for proper roads only, direction on paths and tracks could be rendered with a different shape - a slender triangle perhaps - pointing in the right direction?
