A “Living” spot for small structures (i.e. lean-tos, tents, possibly small huts/teepees,or maybe just a place to set down a bed roll) is absolutely needed. Just next to the fire perhaps, for ease of access.
As for the lean-to itself, I know 1.0 had us make a wooden one, but perhaps 2.0 could allow for more decision: a wooden lean-to could still be made, being a bit more structurally sound/sturdy (but not by much) and allow pine branches to be laced on it. On the other hand we have the example tarp lean-to, which requires just a tarp, twine/string/(maybe babiche?), rope, and a few wood stakes. Less sturdy, but can still keep out the rain.
Now excuse me while I go binge-watch this series XD
