For those who would want to have a separate tag for 'trails', it's exclusive but obviously those who would want to tag everything with highway=path+subtags will disagree :-). I see there are three main sides in this, those who would want... 1. ...highway=path == highway=footway 2. ...highway=path only 3. ...to have additional highway=trail (or similar value) that is distinct from path/footway For those in group 1 adding =trail shouldn't matter very much, it's just another value and as they usually talk about "using the other tags", the actual value of highway=* shouldn't even matter that much to them (unless they would want to do some defaults but most of people who advocate for this seem to also dislike defaults). I suspect that for those in the group 3. it would be agreeable that highway=path == highway=footway if a real trail/path highway value exists. So instead of "confusion and abuse", I see that a bit more convincing consensus might be possible with it than the current lack of consensus. The only real downside from introducing highway=trail for real that I can think of is that (some) data users might need to support that new value, some of the people in the group 2 might be affected (and perhaps in the group 1 too). But then they really need to care about the highway=* value in the first place for it to be meaningful for them! I know some people seem to unfortunately play with two cards with this: on the other hard they say that subtags are the ones that matter but then they oppose hard adding a particular main tag value, which makes no sense to me. -- i. _______________________________________________ Tagging mailing list Tagging@openstreetmap.org https://lists.openstreetmap.org/listinfo/tagging
