I already have this in /etc/hosts.allow:
  rpcbind : 192.168.1.0/255.255.255.0 : allow
  rpcbind : ALL : deny

and removed the allow-all line:
  ALL : ALL : allow

But the question is how to get rpcbind to use tcp-wrappers
in the first place!

Because even with this in hosts.allow, sockstat -46l still
shows:

root     rpcbind    10188 7  udp4   127.0.0.1:111         *:*
root     rpcbind    10188 8  udp4   192.168.1.1:111       *:*
root     rpcbind    10188 9  udp4   *:<some_random_port>  *:*
root     rpcbind    10188 10 tcp4   *:<some_random_port>  *:*

So it's still binding to INADDR_ANY :-(

Am I missing something obvious, or is rpcbind not "tcp wrapped"
by default?
