fishermen and inksacks

the only ways to get black dye at the moment are wither roses(pain to get because you need the wither) or inksacks,which you either need to kill squids(pain to do) or go fishing (pain to do without afk fish farming) so I feel like,since fishermen are well,fishermen and you can catch inksacks,you should be able to trade emeralds for inksacks,plus it would make getting black dye a lot easier,cause outside of wool,black dyed items are hard to get without the dye

thanks for reading,please add this,it would save me and likely lots of others a lot of time
