You'd think something so obvious wouldn't even need to be stated.
You can tell our fans aren't used to paying attention to the rankings this late into the season.
Last year, after most teams had played 7 games, there were 16 power conference schools with 0 or 1 losses. The next week, there were 13. The next week there were 11. Then 9. Then 9 again. Then 8. Then 7.
And that season was on the high end for teams finishing with 0 or 1 losses. It's usually less. Additionally, contained within those 7 teams was at least 1 team from all 5 power conferences, which means all auto bids would have been accounted for with 5 spots left to fill.
So, yeah... don't see a 1-loss power conference team being left out any time soon.
