org-element-ast is already a part of Emacs. The process of upstreaming
in this particular case is simply a question of (1) making the library
more useful outside Org mode; (2) renaming it.

Renaming is trivial.
The main question is making things usable outside Org mode.
And that's where your work is the most valuable.
So, it was me who is waiting for your input before upstreaming :)

No, I did not mean that you should use org-element to generate parser.
I mostly referred to the way you implement the parser where part of the
parser configuration is stored in the AST. But I was reading your patch
very quickly and could have misunderstood something.
