It is standardized because in 2009 the EU told them to either sign an agreement to do it, or have a law to force them [1]
They signed, but most refused to extend beyond 2012 (partly because they saw apple not really playing game), so here come the law. As long as I can keep a single cable to charge everything, I'm happy.
The Common EPS Memorandum of Understanding expired at the end of 2012. The European Commission reported that all of the MoU signatories, "have met their obligations under the MoU," but that most of the signatories declined an EC request to extend the MoU beyond 2012
