ShadowDrakken, that's what forward development
means. In two years time, when Freelancer and the like are looking even more dated, Freespace 2 will just be capable of running at full capacity on 'Normal' video cards around at the time. If you don't intend to upgrade your video card in the next 2-3 years then don't
expect to be able to play the most up to date stuff at it's full capability, as lightspeed says, you don't have to install it, and it's not as if the older maps make the game look unplayable.
And let's face it, the SCP doesn't look like it's close to finished yet, there are big plans afoot, so it's not exactly as if the community can just sit around twiddling it's thumbs waiting for it, there'd be no community left in a very short space of time. So developing improved content sounds like the best way to support the SCP, and if we hadn't done it, we wouldn't know half the problems were there in the first place
