The open-source my friend. First comes first implements. More and more
development platforms use XML files in where they used a binary file
format before. Just for these cases. Git is mostly used with open-source
and/or very new systems that don't have binary file formats. OK graphics is
another thing, I guess.

So you are welcome to it. "git-lock" is available
