Sprinting, base-building and proximity chat are the focus of Subnautica 2's initial patches, with new biomes and leviathans to follow in a proper expansion.
IIRC it would start to break if you made it too big in the previous game (and I’m not talking about the strength reinforcement at depth mechanic; I’m talking about Youtubers like Let’s Game It Out building a tube halfway across the map).
I myself had a base that reached from the surface biome down into the jellyshroom cave, and another on the island with a ladder from the beach to the summit.
