I Think This Makes It Clear NASH Won’t Happen Anytime Soon. The Have A Long Term Interim In Place!

I was wondering just what was going on with NASH, given the deep silence that seems to surround the topic.
It all became clear when I found this page:

eHealth Record PKI Certificate

The Department of Human Services (DHS) has developed an Interim Authentication Solution to support the launch of the Personally Controlled Electronic Health Record (eHealth Record) system on 1 July 2012.
The interim solution is a modified Department of Human Services PKI Certificate leveraged from the existing DHS issued PKI solution which is Gatekeeper Accredited, and as such has adequate protection capabilities to enable trusted connections to the eHealth Record System. This certificate can be used for the initial registration and setup stages of the eHealth Record.
The interim solution at this stage has been developed to meet the expected scale of the early adoption of the eHealth Record, and has not been developed to be used beyond PCEHR. Software vendors and providers, who choose to, can start using the interim solution for connection to the eHealth Record and replace it with a NASH PKI Certificate when it becomes available.
The interim solution has been made available to support the eHealth sites and software vendors that wish to continue to develop and gain experience with early adoption of the eHealth Record.
The interim solution will require healthcare providers, wanting to have early connection to the eHealth Record, to apply for a Department of Human Services eHealth Record PKI Certificate. The certificate can only be used to connect to the eHealth Record system. The certificate cannot be used to connect to the HI Service or the Department’s online claiming channels.

My only question is just why was the NASH Project pushed on with rather than adapt and modify what had already been built and seemed to be working?
A coherent answer would be great!
