Prior to this launch customers ordering multiple connections to increase their bandwidth to/from an AWS resource had to create a virtual interface on each connection for each resource type (either public or VPC). This meant they had to manage BGP sessions for each connection. Many customers ran into limitations where their router could not handle so many simultaneous BGP sessions and were unable to support the bandwidth scale they needed due to control plane limitations on their router. Customers also had no visibility when their ports were on the same router or different routers. It was entirely possible that customers would end up with all of their ports on a single router, when they really preferred them on separate routers for redundancy.
