Many players play like you mentioned above. IMHO this strategy is profitable to a degree but I don't think that keep waiting in order to push or 3 bet jam with the top of your range is the most profitable strategy.
The above hands you mentioned are just monsters
preflop , other type of hands like 98s+ are also considered as standard open shoves but many inexperienced players don't realize it. In CC games this may be a profitable strategy but I don't think that the same one will take you far in a real poker game.
For example I would be more than happy to open shove my KTs in late position with 10bbs and I will know that the play is always +EV.
Take a look at this link , I have shared it many times before , hope that some players will wake up :

Blinded out is something you should avoid , if you push your 5bbs and the players yet to act are deep in bbs they don't have much fold equity so they will call you lighter and a flip is always a flip.The best hand preflop breaks many times postflop.
Hope I helped you a little bit.
