I certainly won't grep user configuration files from package maintainer scripts - that sort of thing causes serious problems in some environments, particularly those with lots of users or home directories mounted over NFS.
There's something to be said for doing a better job of the error message in this case (e.g. pointing people to the openssh-client-ssh1 package), although I'm wary of ending up maintaining yet another long-lived and necessarily-Debian-specific patch.
