Bottle o' Enchanting - Skulk Brewing Recipe Idea

An expensive item should require a hard-to-create recipe. Craft-able experience bottles is something many in the community have wanted for years, but crafting it would be too easy and wouldn't make sense. Since we now have mine-able xp though skulk, what if we could use that skulk in a brewing stand to brew bottles o' enchanting? Adding in a recipe like this would make it hard to get early game due to being locked behind the deep dark, silk touch, and the nether, while still being easier to make for late-game players who utilize a lot of mending. Using brewing stands makes it harder to make in bulk while still being possible to automate depending on how late game you are, and overall just feels well balanced to do in this way. Plus using skulk, the block that drops experience, makes a lot of sense as a brewing component for this item.
