Science needs a short format that is frozen in a certain point (not very far at the life of the text). If you want to change something, great, but those two requirements are very important.

People would also benefit from a large changing body that reflects out current knowledge. But that was impossible until very recently, so every initiative on that line is new. Anyway, that second body can not replace the short frozen format.

If those descriptions makes you think about version control software, well, there are already a lot of comments talking about it.
