Fair enough. I gave it a closer look and don’t think it’s possible to
support even on its own. Try opening a file containing:

  print(1)

Enable treesit-explore-mode and see:

  (call
   function: (variable name: (identifier))
   arguments: (ERROR ( (number) ))      ; That ERROR node is erroneous
   (argument_list (string)))

Those stray ERRORs are pervasive and all kinds of code end up with them
in unexpected places. There may be other issues but this one is enough
to make it unusable. I don’t think this is fixable on the Emacs side.

Another problem is that in an empty buffer Emacs freezes when you start
typing. The Azganoth grammar and t-e-m must be enabled for it to freeze.
This might be fixable in Emacs but wouldn’t change the problem with
misplaced ERROR nodes.

If someone fixes the problems with the grammar or shows where I’ve gone
wrong I’m happy to revisit.
