The development of the reference pool has ENTERED phase 2! The developers still do not recommend making new portable plots for mainnet and keep for officially release (according to the first information their later use has about 75% chance). Official support for the reference pool will be in version 1.2.0. The release date cannot be estimated with any certainty at all, but we expect that a full release of what will be version 1.2.0 will happen during the week of July 5 at the soonest.
