It's not that far behind but there is going to be a time investment for whoever undertakes it. The parser is very modular but documentation is sparse. It follows the EBNF notation quite closely, but adding these anonymous structures will require adding intermediate formats to track them and pass them to the machine code generator. It's pretty heavy work, but not insanely complicated. One of the gating issues seems the existing devs didn't seem to care about these features when I was looking to add them. That may be a problem for someone who does not wish to invest lots of time understanding the codebase.
