A poser file parser is probably the only option short of dev additions to the Poser Python API.
The problem with the Python API is that it has so many gaping holes.
Primarily in the form of an absence of methods for creating items in the scene.

However, creating and linking nodes IS possible, but then the parser hurdle is the problem.

Others have developed their own parsers, but they are not available separately, but bundled into products (PFE for example).

As a caveat, though, first invent a reliable method for human suspended animation, before holding your breath.
I see peripherally how much the devs currently have on their plates, and new features might be fairly far down the implementation list.

I'm not trying to be a totally negative Nancy, here, just an informed optimist (i.e. pessimist). My Poser wish list is bigger than Ben Hur and SpaceX's Booster & Starship stack! :-)
