Yes, it is an issue for sure.
But it's also a world where people have grown accustomed to doing this - automatic scaling in the cloud with re-use of IPs means that systems come up with the same IP frequently, so people have gotten used to doing this.
For the stuff I manage in the cloud I use their APIs to keep my known_hosts file up to date - if an IP got reused by an instance, I clear the entry in my known_hosts file. If it didn't, I would see the key change alert (verified by modifying the host key on the destination server)
