The whole point of this draw is the *output* format of an IPv6 address
(and it's using fairly weak language, like "should" instead of "SHOULD",
at that).

Input parsers need to understand every possible representation, as long
as it's syntactically correct.  This draft doesn't change what is to be
considered a syntactically correct representation, so for a *reader*,
it is just not very relevant.
