Personally, I don't write scenarios specifically
for Harpoon ANW. I write them for Harpoon3 (the previous version). It is far more stable and less buggy. It has its problems but, when compared to the problems in ANW, they pale in significance.
The scenarios I (and some others) write for Harpoon 3 may run in ANW, but there is no guarantee (unless it is specifically reported to be tested with the ANW engine). The scenarios specifically tested with ANW can be found:

http://www.harplonkhq.com/Harpoon/H3scenlist.htmAs you can see, the H3 list is significantly longer.
Speaking only for myself, I don't care if they run in ANW or not. I test my scenarios for the version (H3) that works. If they happen to run in ANW, that's a bonus. I, personally, don't test them with ANW.
However, some kind hearts (usually those folks who have no access to H3) will take the scenarios and test them in ANW. If they report that it works in ANW, that's good enough for me and I tell others about it. Otherwise, I only release a scenario for H3 and make no claims or promises whatsoever of compatibility with ANW unless someone has actually tested it in ANW.
