I agree with Michael...
...except for the one specific case of language codes.
Language codes are a list of values that don't affect anything anywhere else
in the spec, with the single trivial exception of the default lower bound for
arrays, which is already incorporated into the language-code table.
I flipped through Chapter 7 and it's the only case like that, a list of numbers
that have no other syntactic implications and (almost) no semantic implications.
New language codes are rare, maybe 1 per year. No new language code
request has been rejected, according to the resolved-issues lists.
The interval between publishing DWARF 3 and DWARF 4 was 5 years.
I don't see any particular value in waiting 5 years to formally and officially
assign a name/number combination for a language code.
