I am working on an update to the IPv6 address architecture. In doing this I am working through the comments on the previous draft. One comment made was to remove Section 2.5.5 "IPv6 Addresses with Embedded IPv4 Addresses" from the document. This would include removing the special case in the textual representation (section 2.2, 3.).
I would like to solicit the working group's thoughts on this. I don't have a strong opinion one way or another. It's not clear it has ever been that useful and add a certain degree of complexity. On the other hand, it appears in several places in the document and requires some careful editing :-)
It is clear that the mapped addresses are widely used and useful, and a lot of people have raised their concerns about removing that.
However, what I think Bob was referring to was the use of IPv4-compatible IPv6 addresses (::1.2.3.4), and refocusing the section (2.5.5 in rfc3513) to be about the mapped addresses.
I suggest just simply removing compatibles. Those who are interested of them can always look back at RFC3513.
