Lols.  In theory, you're right that it's a bad advice.  In practice, it's
not a problem, especially for:

   1. Brief connections.
   2. Local/trusted connections.
   3. Connection check before securing it.

One should always be aware of security issues, of course, which I briefly
touched upon and suggested using ssh instead for that reason.  The MIT
magic cookie thing would be the next best thing but it's so convoluted
that nobody uses it.

BTW, John, you can add a hostname after the '+' sign to allow connections
only from that computer.  Example:

   $xhost +remote_host_ip_or_name

which would be the next next best thing to ssh -X and MIT magic cookie

My autoshop teacher once told me that a good mechanic always uses the
correct wrench for the correct nut, so a good mechanic should never use
the monkey wrench (a.k.a. adjustable wrench.)  But a good mechanic, he
added, would never be without a monkey wrench in his toolbox.  `xhost +`
is one of those monkey wrenches for UNIX people, and it would always be
a tool I'd teach people along with `ssh -X`.
