Will there be a Novakid themed quest for the main quest or is the way the main stuff is now final. If there isn't going to be one, is there already a lore reason, or will there be one?
Nope, Novakids are not involved in the main quest. I don't know if a lore-friendly reason was given, but the real-world reason is that it's because they were a stretch goal reward.
The current more reason(I believe) is because the novakid just decide not to record their history, and with how scatterbrained they are, they don't remember to pass it through word of mouth.
