I still think it's a silly restriction, but the private address in the case would not be placed into the Well-Known Prefix (and used as a destination address); it would be put into a /64 out of the subscriber's prefix (and used as a source address). So I can live without this change.

Good.

I think that the text should not be changed by an errata. The text is a
fair rendering of our technical assessment at the time. We did not want
to use the WKP to build ambiguous IPv6 addresses, and wanted to make
sure that private IPv4 addresses will be mapped using private prefixes.
It may or may not have been the right decision, but this is definitely
what we intended.
