That's teh advantage of python. You can see and modify the source/script very easily, you don't even have to go and fetch a source package to have a look at what it is doing.

I'd be more worried if it was a binary, and even more worried if the source was closed.

Edit/Afterthought ...
I would say that the possibility of getting hacked/pwned/DOSed is quite high without some means of command authentication, though, but I've not looked at this yet to see what options are available in this respect. This is interesting though.
