Sonar potion for skulk soundwaves

After playing 1.19 for a while, I realized that being able to see the skulk soundwaves in game didn't really make sense. Have you guys considered making them invisible unless you have a 'sonar' potion effect added instead? The potion could be brewable using 'bat tuft' sheered from a bat. this would also add a use for bats as they do not currently have any use (you can't catch them, tame them, or really do anything with them, so adding a potion made from sheered bat tuft/hair would actually give them some reason to exist)
