I'd like to extend this list of fields to include more of the set of properties which are defined in ID3v2 and widely accepted by the Vorbis comment/APE community such as "composer".

I'm open to suggestions on how to implement this, but I think that for xiphcomment and ape, this would mostly be a matter of getting/setting the upcased value. For ID3v2, I was considering following iTunes' example and creating a comment with that fieldname as description.
Consider doing this properly and using e.g. User-Defined Text
Information frames as in part 4.2.6 of the id3v2.4 standard.
Just because iTunes doesn't follow the standard doesn't mean you
shouldn't either... :-)
