New items for discussion

• Does the init-phase of the CCPP assume that model grid information is (or is not) available at that time?
  • This is not explicitly assumed, although SCM and FV3 physics_init phases are called after the grid is available.
  • It would be good to make this explicit in the docs for host models.
  • Can we introduce a new CCPP phase that can be used before the grid is known? (asked by Jesse N. - will start an issue)
• Timelines for PR reviews
  • Email reminders from Repo manager?
• Discussion 518: Setting error codes other than 1?
