I do think there are some advantages to setting the cutoff point just slightly later than birth, even if by just a few hours: *evaluations of whether a person should come into existence can rest on surer information when the infant is out of the womb
non-maternal reproductive autonomy—under the current legal personhood cutoff, I can count this as an acceptable loss, as I consider maternal bodily autonomy and the interests of the child to be more important, but with infanticide all three can be reconciled
psychologically, parents (especially fathers) might feel more buy-in to their status, even if almost none actually end up choosing otherwise, and if infant non-personhood catches on culturally infant deaths very close to births might cause less grief among parents
(All this assumes that late-term abortions are a morally acceptable choice to make in their own right, of course, rather than something which must be legally tolerated to preserve maternal bodily autonomy.)

Perhaps the detachment of the umbilical cord would be a suitably symbolic point?
