[Tagging] What is the role of "role=guidepost"

At least some guide posts are to guide people along a particular route, particularly where a few paths meet, where the route diverges off the main path/road, or where there has been a long distance since the last guide post.

Some of these are simply small signs with symbols only, nailed to a farmers fence post or tree and may be easy to miss unless you are looking for them.


Provided these are indicators of the route I think they should be included in the route relation.
