it is very technically true, but 

- it is an unclear tagging (it is unclear whether it is wide enough to fit car)
- it is a poor tagging for ways accessible to all vehicles - it is almost certainly
rather highway=track or highway=service
- it is terrible tagging for public footway (as this tagging technically allows
cars)

It is also a poor routing as it is basically always mistagging and mapper
almost certainly meant "public footway" not "open to all  modes of transport"

(have you checked is it reported by your favorite validator? If not, maybe 
it is worth proposing to its authors. Also, Osmand likely should not treat such
tagging seriously)

access=private / access=no is often correct

though basically all access=yes on highway=footway is wrong
