The problem with this logic is that the example set by previous biomes saw you getting access to potions using pre-biome ingredients; the poison resistance mead for the swamp only needs honey, thistle, coal, and a neck tail while the cold resistance mead only requires honey, Thistle, bloodbags, and a grey dwarf eye.

Based off this premise, I could definitely see potential precedent for a feather fall potion having been available using plains tier materials and below.

Even then, poison resistance meads aren't really ever replaced; though later on you gain enough armour and quality food that you can often ignore the DoT outside of the bonemass fight and growths.

In this manner I would argue that access to a feather fall potion would have been an excellent intermediary between early exploration into the mistlands and when you can replace them entirely with a a craftable equipment that does the job passively.
