It's significant in that the aircraft was sold on the basis of fuel economy figures that have thus far proven optimistic even with the lightweight battery configuration.

Which I'm sure it will be once the issues have been ironed out.
A 787 without ETOPS is still grounded. Would Boeing even be able to deliver them?
It's grounded at the moment with or without ETOPS, for sure. At this point, nobody outside of Boeing knows precisely what contingency plan is in effect or what that plan constitutes. It goes without saying that the airframes can be ferried without ETOPS - the limitations would only apply in fare-paying service.
