You may laugh. But in an enterprise, it is the CA's job internally to help manage and communicate expirations to users. If there are 10,000+ certs in an org, you want a tool to manage them.
Fair point that it's the CA's job, but typically their solution is "We'll send you emails at certain thresholds". That kind of thing tends to get lost in the noise of daily work, especially at places with poorly defined processes.
I've also worked places that used multiple CAs, and that makes it more difficult to manage. This at least can pull the info in based on what the server is actually using, and puts everything on one screen, regardless of the CA it came from.
