This helps me to figure out some more about how rake works and seeing PostTimestampChanger is helpful because it’s taking me a long while to figure out those internals.
My question started out as “why not just add this rake tool to Discourse?”
My answer is that users:fetch_wp_data isn’t included in lib/task/users.rake because it depends on an external plugin. And then I wondered why bother to delete it, but I think that’s because if we don’t remove it when we’re done, we’ll get into git problems when the next pull happens?
