Exactly. That's the main motive behing the bug report. If removing all
the r* tools is too drastic, I could instead only remove rexec/rexecd
and keep the others in the package. Would that be a better solution?

Yes, I didn't want to got too far in the cleanup.  That's why I kept
things like telnet, ftp and talk even though most people probably use
ssh/sftp and IRC/Jabber.
