That said, the key point Modern Orthodox people are making now is that more permissive or less permissive, the Orthodox conception of when an abortion is required is clearly different than that of the conservative Christians writing the laws in red states today, and we would much prefer a regime like Roe because it meant that deciding to go forward with an abortion was the province of individual women in consultation with their personal religious and moral and medical authorities.

Yes, this seems the most important point from my perspective.

One issue which (I wonder) might have influenced thinking on this back in the 2nd century was the danger posed by abortion at that time. Neonatal infanticide is acceptible in Roman law under certain conditions, which suggests that the personhood of the fetus was highly conditional, but the jurists are leery about abortion because it posed a risk to the life of the pregnant woman as well as because it took the decision to raise the child out of the explicit control of the father.
