After me and Eloy disagree about the situation with blocker issues a bit, there is an idea to:
ask JIRA for all these:
- parents (for subtasks)
And then pass all them into a new "whitelist" parameter.
That would provide us the same solution to the 3 problems. I'm sure the 2 first are possible (via jira-cli) don't know about the epics one (not sure how they are implemented - custom field...).
