l-UAL had unfilled 777 and 400 bids 15 years ago as well. ALPA decided to talk the company into not letting new-hires go to those aircraft. I can't remember why they did this.

I think a new hire being a bunky for 300 hours a year is a bad way to learn to be an airline pilot. Maybe that was ALPA's reasoning.

The 777's are not fenced on either side. Their are some pretty jr folks sitting on great lines in IAH and EWR. Their are a bunch of much more sr 756 FO's that are going to get bumped. I would bet a significant number bump to 777 FO.
