The other 30% are already accounted for - they go to specific parties as per the original distribution. These 70% are the reserve DBC-SNT that will be released by the network over time.
What is being discussed and worked upon here is the method for performing that distribution.
See: https://forum.autonomi.community/t/rfc-0061-safe-network-token-distribution/
For more information. But TLDR, nothing has really changed from the original, just methods of making it all work/function/happen.
