It would be great to see other mods use it. I guess it makes more sense for some buildings to need thatch rather than iron. Pity there is a limit of only 3 different building materials per building though.
I don't know a lot about thatch, but aren't some water reeds used as thatch? Could be interesting to have a reed farm (bigger than the <abbr title="Colonial Charter">CC</abbr> version) that grows reeds/thatch. Another job for <a contenteditable="false" data-ipshover="" data-ipshover-target="<___base_url___>/index.php?/profile/6338-discrepancy/&do=hovercard" data-mentionid="6338" href="<___base_url___>/index.php?/profile/6338-discrepancy/">@Discrepancy</a>, maybe? Or if you are both interested in a reed farm, perhaps the two of you could collaborate on it.
