No, but you're missing out on gil, matters, and units/cap progress. Doesn't appear there's anything currently this will wall progress to, but that could change. Use history as a reference point. When Odyssey was released with segments but no rewards, nearly nobody formed groups. Then they dropped Atonement bosses and everyone was scurrying to get points. It's always better to get progress sooner rather than later, but the model for Limbus looks entirely different as casual content, so it's maybe not the same kind of situation.

Theyre adding the last update with new nms, certainly, it will cost units to spawn

That's your possible point of friction

I think that doing a moderate amount of runs to raise cap is probably worthwhile if you are worried about falling behind and being undesirable. If they introduce content that rewards (or costs) very high amounts of units to ease the grind, you'll wish you had.

Matters, whatever. It's a long grind, it'll probably be eased in some way at some point, and I doubt future content will rely on you having done them past the value of the gear itself.
