Ideas of questionable quality

[Mouse]

Distinguish between and separate space resistance and cold resistance.  Finally ditch the obtuse and poorly-documented "spaceworthy jumpsuit/outer suit + spaceworthy mask/hat = 100% cold resist regardless of stats" mechanic without balance concerns.  Let wolves be cold immune without having them zooming around in space with a jetpack.  Let lings spacewalk but still not want to get frozen solid.  Introduce liquid nitrogen without immunity to it being trivial to get.

Potential downsides include even more text in the tooltips (although we can probably ditch disease resist now) and no longer being able to spacewalk with fuzzy slippers/speedo/bathrobe/boxing gloves/horse mask/viking helmet.
