The clause setaccess=no will not work if the way has a tag like vehicle=yes or foot=yes, as it only sets the mkgmap:* tags.
That's an interesting point. In the US, it's almost 100% true that a highway=construction is also more or less marked as "no trespassing". So highway=construction foot=yes sounds funny to me. Highways under construction are scary places with heavy equipment and large amounts of dirt are moved around all the time. I would expect to get maybe almost arrested if walking in one, or at least told to get out and stay out. But if there were a highway project that was unusable by cars and people really were allowed to walk on it, then that could make sense, and I could see it being added to routing with car=no and foot=yes. (If the road is usable, then it isn't highway=construction.) Are there really situations like that (as opposed to a path alongside the construction)? I am asking because if it's just that 'highway=construction is completely ignored for routing' is good enough, it's probably easier.
