My Suggestion: just Mark landable areas and have waypoints only for windsocks (really in place).
Why:
1) A landable place ist not always and ever landable. WHO guarantees, that a landable, ist safe?
2) I am not sure if a landable waypoint File is really a contribution to safety. In my experience it is safer to assess landing Options visually than to calculate reachable outlanding options from waypoint files. The latter allows the Pilot to Push the Limit more effecively, which does nit result in a safety gain.

This one seems obvious. Fabien mentioned using more restricted sportive airspace on too large unlandable places.
