You've made a pointless add-on, that's the problem.
We just learned about this future change 2 weeks ago. You have no idea how it will be implemented, and your add-on certainly won't have any part in it.
You know the problem with it? Public trusted terrain is useless right now. First, it's not yet fully efficient, and second, the purpose of this is destroyed with people building their own terrain. There aren't even repeating capabilities yet.
That's why this add-on is premature.
