I agree that you can't really play very passively with the Soul Ripper, but people don't often want to chase things with their ASF into enemy territory over potential SAMs. Having the Soul Ripper disappear from T3 radar coverage if it does get away is still helpful because it means the other team's air can't have ASF in a good position to intercept it all the time. You could also bring it back to your base and control-K it without people knowing, etc.
This wouldn't be a major change, but that's why I think it should be a no brainer? It's a mediocre unit that nobody would be mad to see get a small buff like that which has factional flavor and could lead to more exciting games-- we all know that people don't scout as much as they should and having a Soul Ripper appear out of nowhere with a cloud of stealthed Gemini around it to snipe an SMD or something would be cool.
