For one, nothing about this project makes "every law" a commit. It just takes the _annual_ snapshots published by the House clerk and diffs chunks of those files against each other. A project which actually traced the edits in each annual snapshot to a specific passed bill would be incredibly cool (and is probably tractable now for the first time with current AI agents). This is not that!
All this does, as far as I can tell, is parse a set of well-structured XML files into chunks and commit those chunks to Git. It's not literally nothing, but it's something that the author's own README credits multiple people doing years ago with ~100 line Python scripts.
I don't mean to be overly harsh. But this is exactly the problem with treating your software as a "factory": you release something you do not understand, in a domain you did not care to learn. And we are all the poorer for it.
