As far as I recall, the reason the warning was added to the manual was
that it's fairly heavy on resources to implement that way (especially
back before the wrapper support was added to sshd; running it out of
inetd added quite a bit of lag).  It is also liable to problems from the
idiosyncratic configuration syntax.

By and large, you'd be better off with a firewall, but hosts.allow will
certainly work if you want to do that.
