Pandoc Lua Filters

I've always wondered if pandoc can be made reactive. Say markdown to Pandoc AST.

If one changes something, a quick update to the AST would happen incrementally.

Now with all these llm I might actually see if it can be done.

Is there anyone feeling that Pandoc is ever increasingly bloated? I have used Lua filters a decade ago [1] and the current documentation is nothing like my memories. I'm not even sure that how much of Lua scripts remain compatible across different Pandoc versions.
