I don't know that I have faith in the AF to manage this correctly, either.
But the sky is not falling because of this choice.
I am a late rated guy, with more than two different AFSCs. I was nearly 7 years time in the AF by the time I got to my first flying unit. I was not a CAF guy and honestly probably would have had progression issues at that point in my career, if I had been. There were some issues...but I have had awesome opportunities along the way, including leading Airmen as a commander twice and both times in combat. I continue to have the opportunity to fly at this point in my career and will probably be able to fly until I retire. It has been a great ride. The only constant is that, no matter what Chang spews, the AF gets rated policy wrong more times than not.
All of the current fixes will make a dent. None of them will fix the problems alone. They probably won't fix it when all implemented together.
When in doubt, refer back to how the AF doesn't get it right most of the time.
