Our organization, like many others I presume, have a limited need for multi-user editing. We have an enterprise geodatabase that meets the needs of our users and we use ArcGIS Online. We do not need another "local ArcGIS Online". We don't want to have more servers and software to manage...the Portal cost/benefit is quickly increasing. We have been using the ArcMap Parcel Fabric for many years, and we like what we've seen of the new ArcGIS Pro Parcel Fabric. Assuming that Portal really is based on ArcGIS Online and packaged for local use, it would be interesting if there was an option to host your ArcGIS Pro Parcel Fabric in ArcGIS Online so that those of us that use ArcGIS Online with no other need for Portal could still utilize a multi-user version of the ArcGIS Pro Parcel Fabric without having to install, manage, and maintain Portal. To my mind having more than 20 years of experience with ESRI products, the requirement of Portal for multi-user parcel fabric editing is a significant blunder, and impedes the adoption of otherwise valuable technology. Perhaps this suggestion is a relatively simple solution to that.
