Ink Sacs and Glow Ink Sacs to brew potion of blindness and glowing

The squid and glow squid are cool aquatic mobs that roam freely in the oceans and deep in the caves, respectively. However, I cannot help but believe that the ink sac should be used to brew the potion of blindness. Since squids do release ink when attack to run away from an entity attacking it, why not use the item to brew that potion.

The same can be applied for the glow ink sac but it should be used to brew the potion of glowing. Since glow squids' glow on their own and the item helps with texts and item frames glow, why not include use the item to brew that potion. It would make sense and could help put in multiplayer combat.
