Eric and all, I do not think that this Erratum reflects any real issue. Technical or editorial, with RFC 4364..
The original text in the RFC, IMHO and FWIW, simply means that the VPN architecture does not require a dedicated SAFI for routes with the NLRI comprised by an 8-octet RD followed by an IP prefix but not containing any labels. At the same time Section 10 discussed both advertisement of unlabeled IP routes (in what is known as Inter-AS Option A) and labeled IP routes (in what is known as Inter-AS Option C). RFC 4264 (and its predecessor RFC 2547) have been implemented for many years and widely deployed. There are multiple deployments in the fields where implementations by different equipment vendors successfully interoperate. AFAIK during all these years the text in question has never been misinterpreted causing interoperability issues. I suggest rejecting the Erratum.

Is suggested to be replaced by " Note that this VPN architecture does not require the capability to distribute unlabeled IPv4 addresses. With the errata reporter note: From my understanding, VPN-IPv4 addresses are necessarily labeled, but IPv4 adresses are not indeed. Section 10 seems to confirm the error by using the correct term: "distribute unlabeled IPv4 addresses to each other."
