It wasn't entirely clear what should happen to the FCP timer (and state) when a concern is raised during FCP. After some discussion, we agreed that when a concern is raised:
1. FCP will continue to not conclude until at least 5 days have passed, but once those 5 days are up it *still* won't conclude until all concerns raised during FCP are resolved.
2. If a concern warrants a large enough change in the document, then the Spec Core Team may consider cancelling FCP and restarting the timer in order for people to have some time to think about and review the new changes.
