Sometimes it's the companies that dictate standards. FD is notorious slow mover, yet it's 'an industry standard. I worked on one script with another writer. At that stage it was only two of us drafting the idea and I had a need to see what has changed in a script since I sent him my last version and vice versa. I mailed the dev of Fade In if he could just include a diff (yes, our beloved diff) somehow inside of Fade In. A day or two later it was in. I use it now constantly. Same ol' diff we're used to, kind of looks same as on github as well. Red and green lines and all.
This is an industry with lots of resources and a keen eye on new technologies. If you come up with something that optimises anything in workflow, it will come to open hands.
If you want to make it happen right away, make a royalty free stock footage archive in 4k of various snippets of code with metadata on what it's for. Less work=more adoption.
