I suggested this before, when pointing out that Skills have become superfluous - a legacy mechanic - and that it would be possible to replace them entirely with Discoveries and Skill Values, maybe even giving villages themselves a tech/culture tree!
Focusing the entirety of your LP into Skill Values was a welcome part of the original Study system. That progression felt much more natural and easier to explain than dividing LP between both Skills and Skill Values. (And these two mechanics having such similar names can be confusing for new players!!)
Unlocking an entire group of recipes by purchasing Skills seems more restrictive and unintuitive than the system could otherwise be. What exactly does a Wicker Breadbasket have to do with Hearth Magic or Carpentry? Why must one learn Animal Husbandry to discover ropemaking? Why must one learn Fishing before learning to Swim? Why does learning Glassmaking not unlock the bottle and glass recipes? What about when they add regional materials down the line? What if existing items are given additional uses unrelated to the skill they require, as ropes were? Tying bottles to Winemaking/Beermaking makes about as much sense as tying jars to Prospecting or Cartography!
The game not bothering to inform you of new unlocks does not help anything!
