Ok want to focus the discussion on one question. Proposal: DAG.max_active_runs will apply to non-backfill dag runs and will *not* apply to backfill dag runs. Backfill.max_active_runs is a required param for backfills and is evaluated entirely separately from DAG.max_active_runs. In other words, DAG.max_active_runs is not considered at all for dag runs that are part of a backfill. Only the max_active_runs for that backfill is considered.
Sound good?
