While i do see its uses being limited, it’d be absolutely amazing for mid-game in space age where for when you unlock Epic quality - I dont want to have to go around reworking all my setups to handle a new output, so i’d much rather just be able to tell my machines to only ever make rare items.

(I could also seeing this be even more useful in mods, where more qualities are added and therefore more possibility for buildings needing to be retrofitted)
