@magik6k We had to do this just so we could use the itest framework for a migration test, which is not really what it's intended for, but is better than any of the existing frameworks we have (I think). Questions for you:
- Do you absolutely hate it and refuse to merge this PR?
- Is there a way to not expose this method over the JSON-RPC, and have it just for things like this test?
- Do you have a better way to write this test?
