To be honest, I'm not too concerned. Making it a git repo makes the history more readily available, but a bad actor could still get it from internet archive or other archive sites. And if the concern about forking is that someone could impersonate you, they could do so with a few extra steps by just looking at the rendered HTML of the README. I know there's something to be said for making malicious behavior more difficult to achieve, but in this case the amount of extra work someone would have to do is minuscule if this weren't implemented as public repos.
