WordPress (Ill-Advised) Hack: I Already Load jQuery "Manually"

/*
 * Plugin Name: I Already Load jQuery "Manually" Hack
 * Plugin URI: https://gist.github.com/2951506
 * Description: If you already load jQuery manually (i.e., without using WordPress' script API), this plugin will prevent other plugins that *do* use WordPress' script API from "double" loadin jQuery.  There are probably better ways to prevent this unwanted double-loading behavior.  If you have to use this plugin, you're probably doing_it_wrong().  Use at your own risk, it probably breaks something.

if ( !is_admin() ) {
	// Hack: This reregisters the 'jquery' handle as a "group" instead of script.
	// That way, a script tag won't be printed, but wp_print_scripts() won't
	// treat the 'jquery' handle as missing, which would stop it from loading other 
	// scripts that depend on jquery 
	wp_register_script( 'jquery', false );
}

This is a proof of concept. I wouldn't use this :)
