Seeing the photo, knowing what I know and from this topic (humans, always in learning mode), it wouldn’t be my initial inclination to tag the beautiful way in the photo as highway=path, I would start with highway=track tracktype=grade2. Any hiker would be glad for such a couplet of tags.

But at the risk of repeating myself, only knowing this is a European (to me, from a USA perspective) highly-engineered (over-?) way in OSM is why I would not tag this highway=path.

Yes, I do nod it is a super-duper so-called Autobahn version of a path, tagged for emergency vehicle access, as it is: unusual, a “super-class path.” If it could receive thousands of hikers suddenly descending upon it, OK, they could walk “many abreast” (wide). I wouldn’t call that a path (initially), you might, looks like you do. It’s unusual, my mind is expanded realizing the tagging captures the unusualness of this (to me, a bit, at first). Still wrapping my head around it, because it’s like another footnote I must have tucked behind my ear of “sometimes, super-duper thousands of hikers in a bunch Autobahn-style paths are found in central Europe.” Noted.

It does get to be choreful with footnotes and exceptions to rules. Rules (especially when they work well), yeah, awesome. Exceptions, yeah, those sure can slow things down.
