There is no reason not to keep ABNF as specific as possible.

Saying that
ident-type =  "ppt" EQUAL ( token / ( DQUOTE token DQUOTE ) )
leaves no room for misinterpretation.

There are quite a few people who use ABNF grammars to create field parsers
or validators. Providing them with the most specific grammar possible makes
their job easier.

As far as other changes are concerned, I would suggest getting an open
interop event organized. Based on the results, it is possible to see all
the issues or pain points with the current specification and decide if a
specification update is necessary. If the group sees a clear need for a
document update, we can update some of the design limitations of the
current specification.
