@A_smart_kitten proposed the following:
(side note @jnuche, if the bot is flagging a closed security task as a train blocker, should it also reopen the task in question for additional visibility? i’m just thinking to avoid the potential risk of people seeing an already-closed train-blocker-subtask, and - based on its 'closed' status - thinking that the train-blocking issue has already been resolved.)
I'm in favor of that. Pinging @thcipriani and @sbassett for visibility
