I agree with you, it's really an important announcement, and I think it's also very interesting what Midas said about why Phore was selected, see bellow:

"Phore (PHR) display the core qualities required for inclusion to MNI - 1) history of developmental progress, 2) long term coin stability and sustained price, 3) professional core team and 4) strong coin economics. As well as this, PHR is one of the top rated coins on Midas and their inclusion to MNI brings greater strength to the long term prospects of the Masternode Index."
