Well, speaking for myself, it has been my desire to create a game that I wouldn't mind playing with my children. For that, I have wanted to keep the language relatively clean. However, the degree of harsh language is largely regulated by the voice actors (we do not require them to say anything they aren't comfortable with saying). That's where that line came from (I'm the voice actor on that line).
Other characters will use some language that is a bit "saltier." However, I think our major goal (or at least my understanding of it) has been to stay within the general parameters of the official Wing Commander games. So, there was no strategy from the team as a whole along the lines of what you were suggesting per se, but that is consistant with my particular approach to the voice acting.
