What 'are the alternative parenting arrangements and circumstances?
Do you mean Foster Parents?
Schools, Tutors, Nannies?
Adoptive Parents?
I'd suppose myself the importance is 'blood, a shared trait between that more closely aligns oneself to one's parent or child.
. . .
Depends what the 'purpose of raising the child is,
"Ottoman officials would take male Christian children, aged 7 to 20, from Eastern, Southern and Southeastern Europe, and relocate them to Istanbul,[16] where they were converted, circumcised, assimilated and trained to serve into the Janissary infantry corps or palace duties."
Possibly the state found this arrangement ideal, provided they were able to properly indoctrinate, train, and use said children as soldiers.
. .
Though I don't know if such soldiers would tend to be better or worse for various purposes.
Might mess them up in values and social development, that they might not have been suited to all positions of soldiering.
Maybe pissed some of them off against the government that did such to them.
