Yes, but we should encourage people to add as much information as is available from reliable sources that have a license compatible with OSM. Of course, the best course of action is to travel on the path yourself and take lots of pictures, videos, and notes. However, not everyone is willing to do that, and that is ok.
In the US we would call that “exposure”, that feeling you get in your gut that when you look over a ledge to a surface far below, whether or not there is a danger of falling. I don’t think we have a tag for that in OSM.
If one is planning a hike, scramble, ride, or climb, and the sources you have do not provide adequate information (e.g. a OSM highway=path with no other tags) you should seek out additional sources until you are confident that your intended route matches your skills, fitness, equipment, and desired level of adventure. Very few maps in my experience provide this. This may be due to the fact that it is difficult to convey all of this information with a limited set of symbology. I find it usually necessary to consult a guide book (often nowadays that is an online guidebook).
