Honestly, I do not think berries should be farmable, only on the premise they are also crafting ingredients for banners. Banners are pretty special, and farming berries though it makes sense I think would deflate the meaning of banners, the meaning of tamed animals, and the overall meaning of berries, they arent a great food source, and can be tedious to grind if you didnt stockpile early on for taming but overall I disagree as far as berries, however new fruits and plant types to grow im all for!
