First, I believe to each his/her own. For me, I won’t get into other peoples parenting, as long as the child(ren) are not being harmed/abused. We all have our own ideas and am sure all of these pantless kids will turn out fine.
However, for us, our son (25) was raised since a baby as we are. To us, walking around or eating at the table in a diaper, is the same as us sitting in our underwear. We don’t walk around or eat in our underwear, neither is DS. We also didn’t Feed baby food out of the jar, we used plates/bowls, even as a baby. I tried nursing DS but it ddn’t Work out for us. So, bottle feeding he was always in my arms, not a bottle propped up. Now, stating this, I don’t expect all to agree, but it shouldn’t matter.
