Having the HTTP POST data set vars in the page willy-nilly is exteremly dangerous.  You never know how something got set, and anyone who has seen the source could find a way to pass in malicious variables and values to your scripts.  Yes, initting vars carefully helps but...

A feature that allows us to have FORM vars appear ONLY in the global HTTP_POST_VARS array (and not set local variables as now) would be GREATLY appreciated.

It already exists.  Turn off register_globals and turn on
track_vars.
Read the php.ini-dist file supplied with PHP 4.0RC1.
