You could try to make that case either way, but as has been pointed out by others all over this thread, the system we've landed on (90/+30) is industry standard after over two and a half decades of experimentation.

Anything else inevitably has worse for the public good.

Having spent that entire time and then some on both offensive and defensive teams, I assure you longer delays after notification do NOT decrease the overall risk to the public.

There's a reason we've landed where we have as a security community.
