Bad wording (re temperature) from me as i'm working, but yeah, you're quite right, it's only temporarily removed; i was just generalising re the "new players" comment, my point is purely that those 2 things worked real nice in A20 & A21, then became "tame" ie not very good in v1.x ; but anyways, hopefully both will indeed be fixed along the way.
p.s. for me personally (pre 1.x) i always ignored the icons for hot & cold, i always had too much to think about in desert and the snow biomes (angry animals) to worry about temperature ; and indeed, once the angry animals were either dealt with or run away from, i soon realised the temperature effects had no massive bearing on things
