It's fully upon ASU to see if conference champs continue getting byes. BSU is going to get ass-hammered by Penn State, which probably will result in a G5 team never getting another bye. If Texas does the same to ASU, we could see all conference winner byes go by the wayside.
Having said that, are we sure byes are actually that important anyway? I mean, yes, it's one less game against a good team, but if you're a team in the running for a bye, the worst you're going to get is a home game, then you get a week and a half off. I could see it working in the favor of the team that didn't have a bye, as they go into a neutral site game having played a game in the last 3 1/2 weeks, while the bye team risks being rusty to start the game.
