No, that's a step down a terrible return to pre-Civil War policy. We should be actively fighting against enslavement and for due process, not throwing our hands up and saying "well, guess we can't [bring them back from El Salvador, have a sane policy with respect to families, have people's rights to citizenship and legal residence respected]".
The real solution to this is to end jus solis.
Separating children from parents is incredibly cruel, inhumane, even.
