I think when you have to explicitly ask "What are your pain points with X", rather than being able to passively gather these opinions from your own experience or those of others (through blogs, social media, and personal anecdotes), it likely points to X meeting the needs of its users and not being ripe for replacement. So, with that being said, to the OP, I don't believe that CL being old is a good enough reason for it to be replaced. What do you find is lacking with CL?
