A "derail" doesn't mean the project is dead. It only means that the ARC will have to vote and issue an opinion. The word "derail" relates to "fast-track" -- a fast-track is a case that's "on the fast track to approval", while the "slow track" means that there could be an actual meeting, a vote, and an opinion.
That's all. It's _not_ a bad thing unless the i-team is in a hurry and can't wait to have a scheduled meeting, vote and opinion published. Nico --
