Kelp collision physics

Darwin-Evolution

I've just finished playing Abzû which is an underwater adventure game released quite recently. It is amazing, I reccomend you go play it. But anyway, it has a feature which I would like in Subnautica, but please don't focus on this at all because I can see months of programming going into work. Something which is slightly bugging me in Subnautica is that the Creepvines (not so much the bloodvines because they seem more rigid) always stay vertical no matter what collides into them. This is something that Abzû "fixes": its kelp actually sways in the currant, and it folds when any creature or the protagonist collides with it. This feature is also almost present in Endless Ocean 2, which came out in 2009 ("almost" means the kelp doesn't actually collide with the character but with the camera in 3rd person).
This is a feature which I would love to see for the Creepvines in Subautica, but again, the devs should not focus on this too seriously as I'm expecting it to be extremely difficult to program. I just want the idea to be out there. What do you think?

its probably an animation thing, and wouldnt be hard to program sway, but collision would be.

Just though about something which might get in the way of this idea. You can physically go through the kelp, even with a seamoth or cyclops. But there is one part of the kelp which has a physically present entity cell, and that's the seed clusters. The seamoth can't drive through those, it just crashes into them. If the kelps are gonna have collision effects, I think the seed cluster collisions will have to be modified too, and I have no idea how to do that.
