[pct-l] (correction) Why don't we wee more Thoracic bags (front packs / balance pockets / bodypack) in the Industry?

I would suggest you can get much of this benefit by proper loading of a pack.
Things like:
put heavy items against xxx YOUR back
NEVER put your water in the back pocket (put it in the hydration sleeve even if you don't use it there)
use waist band and strap pockets

I've tried this wrap-around style of pack and ran into 2 problems:
1) overheating
2) shoulder fatigue
