Yes, I only meant that as an absolutely hypothetical "if I had a time machine
and could design it a different way...", I realise it would break everything to
change it now.

Do you mean like this?
session_start();
if ( ! $_SESSION['initialised'] ) {
$_SESSION['initialised'] = true;
foreach ( $this->session_init_vars as $var => $val ) {
$_SESSION[ $var ] = $val;
}
}
That should work as long as you don't run session_start() outside that
function, and centralising that is already necessary to avoid "already started"
errors.
