I'm wondering if this is actually still true. Can anyone confirm this?

It's a mis-assumption that session_register()ing a global variable
put's it into $_SESSION in the same request.

Sessions never behaved this way.

The documentation should be clearer on this, reclassifying.

This code don't work properly: 

----
<?php
session_start();
if (get_cfg_var('register_globals')) {
  if (!session_is_registered('step')) { 
    session_register("step");
    $step = 0;
  }
} else {
  if (!isset($_SESSION['step'])) {
    $_SESSION['step'] = 0;
  }
}
echo $_SESSION['step']++;
echo session_encode();
?>
<br><A HREF="<?php echo $_SERVER['PHP_SELF']?>">Reload</A>
----

If register_globals is On, reload will increment counter. 

If register_globals is Off, session will "read_only" like. 
It create session file with zero length. Any write not occurs. 
session_encode() returns a empty string;
