I thought I was pretty clear? It would be nice to be able to call functions from org-mode and its related packages without having Emacs installed, or with some minimal subset of emacs meant for the commandline which caters to the needs of people running headless commands. It would solve a whole ton of issues for me. In particular, org-roam-ui is amazing. To run it, I have to open emacs and then... have emacs launch it into a browser for me. But the hosted interface won't export to anything that can be statically (or dynamically, really) hosted, so I can never access this awesome note-viewing interface from the web, even though to do it locally I already have to use a browser?

I have a project for hosting org-roam-ui as a website that took a ton of finagling to figure out and is extremely brittle. I had to finally load a custom .el script to prepare emacs to even try to evaluate the 'org-roam-ui' command from the commandline. If emacs prioritized headless / cli operations, this wouldn't have been such a nightmare, but it absolutely was. Just finding the right ports and re-assigning them to get out of each others way was a huge learning curve even for a seasoned emacs-er.

No, it's not. It's wishing for basic functionality offered by all other markup languages of which I'm aware. That includes latex and everything supported by pandoc. Org-mode can do all sorts of crazy rendering tasks from its files, and it is worse than pulling teeth to get that functionality into a build pipeline of any kind.
