1 issue with getting anything reverted that we face is that airpoog is a really high level technique so it effects a ridiculously small number of people in the TF2 community. With the past demo nerf it effected everyone that enjoys demo. Also if the TF2 subreddit is anything to go by, the rest of the TF2 community is sucking valves cock right now.
Also when it comes to buffing the sticky jumper all that needs to be done is make it so that only 2 PRIMED stickies can be out at one time, which would be the easiest fix imaginable. Sure this will kill of the triple and quad air sticky but that's just a silly gimmick anyway.
