Celebrate? No. But lets extend the analogy - under the first law, a million children will be killed in a year - under the 2nd, 200,000 of those will be saved. Is the first law better than the 2nd or not?
Make that “is the 2nd law better than the first or not?”
If a daughter of mine was the baby in question - who could legally be killed within a 5-month window under the new law - I would not accept that.
