Removing the "search by image" function and replacing it with lens, a severely crippled tool that isn't even useful for the same things, is a prime example of fixing something that isn't broken. Search by image helps me search for where a SPECIFIC IMAGE FILE has been posted elsewhere and find LARGER SIZES OF IT. Google Lens lens you, idk, sorta, maybe find a like thing to a PIECE if an image, like what shoes a person is wearing. Even if it worked well, they are TOTALLY DIFFERENT USE CASES!
