CodexGen is in tricky place. It got very little traction by itself and by now its role was pretty much reduced to be prototype for http://queryposts.com
On other hand QueryPosts is not (and will not for a while) focusing on data export features.
I am hesitant to keep two in sync functionally, since that adds a lot of CodexGen maintenance effort for very little usage that it sees.
At moment I would recommend just to create your own code for output. Since CodexGen is very modular with ton of reusable code, something like Codex_Generator_Phpdoc_Parser::parse() will do all the heavy lifting for you and you only need to work a bit on template to present data.
Thanks much for the input, I’ll share any code I write for it if it seems useful to your project.
