There are services (external, secondary to the published acts) that published a re-unified, highlighted version. I would imagine a repository that maintains a current unified text, with the "update acts" as commit messages (or even with the original PDFs somehow linked to the commits. I'm sure it can be implemented somehow in Git plumbing. Annotations, maybe?). I'd even pay for this kind of service - but probably not as much as lawyers who need it for their daily work pay for the existing equivalents.
