New certification requirements want them to be able to take-off with
two out on the same side at max gross. The A380 for example will have
to be able to do that.

That will never happen. Now..you might mean "continue the takeoff
after V1", but the aircraft cannot accelerate to V1 at maximum
weight and remain on the runway with only two engines on the same
side operating. In fact, the 747 cannot do it on three engines at
maximum weight. It can however continue the takeoff after V1 if one
engine fails at maximum weight.
