Renaming it shouldn't break anything. RenPy can check for files (for example, some incest patches are actually just blank files with a specific name, and when the code the dev put in checks if it's there, it'll turn the incest variable on) but beyond that, the file names are pretty much just for organization. So as long as you don't give it a name of an already existing file and end up overwriting it, it should be fine.
Also, I haven't played 0.2 yet, but I thought the dev was fixing the text for this version (or did they mean the next, next version?).
