You're right in that the quality of this stuff is average at best due to the source material- I'm pretty sure that's why these weren't considered for the official DVD release.

However, it's nice to have the original, contemporary documentaries and trailers preserved in the best possible transfer, because no matter how "made-for-TV" those docs and features were, they're what we remember watching from our childhood days, and I guess that's why a lot of us are here on these forums in the first place.
