The windowpane thing is real but you dont actually need to knead to get there. I do 80 percent hydration all the time with just stretch and folds every 30 min and it holds up fine, no puddle. Yeah if you dump wet flour in a bowl and walk away for 4 hours thats gonna be soup, but slap and folds build plenty of strength without kneading. The flour matters way more than the method honestly, weak flour is gonna fight you no matter how much you work it. I think the bakery thing is fair but commercial mixers do a lot of that work for you, doing it by hand at home is a different deal.
